The reaction of zirconium salts with meso-tetra(4-carboxyphenyl)porphyrin (TCPP) in the presence of different modulators results in the formation of a diverse set of metal-organic frameworks (MOFs), each displaying distinct crystalline topologies. However, the synthesis of phase-pure crystalline frameworks remains challenging due to the concurrent formation of different polymorphs. The acidity and concentration of the modulator greatly influence the outcome of the MOF synthesis. By systematically varying these two parameters, selective framework formation can be achieved. In the present study, we aimed to elucidate the effect of modulator on the synthesis of zirconium-based TCPP MOFs. With the help of powder X-ray diffraction and scanning electron microscopy, modulator candidates and the optimal synthetic conditions yielding phase-pure PCN-222, PCN-223, and MOF-525 were identified. H-1 nuclear magnetic resonance analysis, thermogravimetric analysis, and N-2 gas sorption measurements were performed on select MOFs to gain insight into the relationship between their defectivity and modulator properties.

Separation of bovine serum albumin (BSA) and hemoglobin (Hb), two proteins with almost identical molecular weight, has been a big challenge for more than two decades. Using traditional ultrafiltraion membranes separation of these proteins is possible only at the isoelectric point of one protein via electrostatic repulsion between the membrane and the other protein. Here we introduce an integral asymmetric isoporous membrane from polystyrene-block-poly(2-hydroxyethyl meth-acrylate-ran-2-(succinyloxy)ethyl methacrylate) (PS-b-P(HEMA-r-SEMA)) having random-OH and-COOH groups along the pore walls prepared by a method which combines solvent induced self-assembly of the block copolymer and nonsolvent induced phase separation (SNIPS). The membrane consists of soft isoporous channels due to swelling of the P(HEMA-r-SEMA) blocks in a hydrated state. The effective pore size of the membrane in a hydrated state is significantly lower compared to that in a dry state. These soft channels allow the permeation of BSA while retaining Hb at constant pH 7.4 where both proteins are negatively charged. In comparison to 22 commercial and in-house prepared membranes the PS-b-P(HEMA-r-SEMA) membrane presents unprecedented ideal selectivity of BSA over Hb (psi(BSA/Hb) = 16). Unlike the conventional technique in this case the electroneutrality of one protein is not mandatory which will provide significantly easier handling.

An article Superior activity and selectivity of multifunctional catalyst Pd-DTP@ZIF-8 in one pot synthesis of 3-phenyl propyl benzoate WOS:000463348300036 published article about METAL-ORGANIC FRAMEWORK; ZIF-8; PD; NANOPARTICLES; HYDROGENATION; BENZYLATION; OXIDATION; STORAGE; SURFACE; PHENOL in [Malkar, Radhika S.; Yadav, Ganapati D.] Inst Chem Technol, Dept Chem Engn, Nathalal Parekh Marg, Mumbai 400019, Maharashtra, India in 2019, Cited 41. The Name is Benzoic anhydride. Through research, I have a further understanding and discovery of 93-97-0. Name: Benzoic anhydride

The catalytic efficiency of zeolitic imidazolate framework (ZIF-8) has been explored by making it multifunctional. Dual active sites were incorporated such as acid (dodecatungstophosphoric acid, DTP) and metal (Pd degrees) to prepare 5% Pd-DTP@ZIF-8. DTP was encapsulated inside the cage of ZIF-8 by in-situ and bottle around the ship approach whereas Pd was loaded ex-situ by simple wet impregnation method. The catalytic efficiency was tested for one pot synthesis of 3-phenyl propyl benzoate (3-PPB), a perfumery compound, from cinnamyl alcohol and benzoic anhydride. Trans-esterification of cinnamyl alcohol with benzoic anhydride gives cinnamyl benzoate which on further hydrogenation gives 3-PPB. Three different supports were screened such as ZIF-8, K10 and MCF out of which ZIF-8 showed the maximum activity because of its high surface area and smaller pore diameter. Further Pd, Ni and Cu metals were studied for selective hydrogenation of C=C bond among which 5% Pd-DTP@ZIF-8 gave almost 98% conversion of cinnamyl benzoate to 3-PPB with 93% selectivity. Fresh and spent catalysts were characterized by various techniques. 5% Pd-DTP@ZIF-8 showed anti-leaching property with great thermal stability. The turn over frequency and turn over number of the catalyst was observed to be 0.058 s(-1) and 835, respectively. A kinetic model was developed with good fit using LHHW mechanism and the activation energy calculated as 17.45 kcal/mol for hydrogenation step. Thus, the reaction was found to be kinetically controlled. The entire process is green.

Herein, we report a redox-neutral Ni-catalyzed cross-coupling reaction of two readily available precursors to produce the corresponding ketones that are an important structural motif in numerous biologically active entities. By the use of a commercially available nickel/Triphos catalytic system, a range of easily accessible alkenyl primary alcohols and aryltriflates can be converted in a rapidly assembled fashion to valuable ketones with good yields and wide functional group tolerance. We also demonstrate the utility of this transformation by late-stage functionalization of a large set of complex molecules with good efficiency, which offers a distinct entry to more functionalized aromatic ketones.

A one-pot procedure for deprotecting carboxylic esters under nonhydrolytic conditions is described. Typical alkyl carboxylates are readily deblocked to the carboxylic acids by the action of aluminum powder and iodine in anhydrous acetonitrile. Cleavage of lactones affords the corresponding omega-iodoalkylcarboxylic acids. Aryl acetylates undergo deacetylation with the participation of the neighboring group. This method enables the selective cleavage of alkyl carboxylic esters in the presence of aryl esters.

A mild one-pot protocol for the synthesis of symmetrical biaryls by sequential Ir-catalyzed C-H borylation and Cu-catalyzed homocoupling of arenes is described. The regiochemistry of the biaryl formed is sterically controlled as dictated by the C-H borylation step. The methodology is also successfully extended to heteroarenes. Some of the products obtained by this approach are impossible to obtain via the Ullmann or the Suzuki coupling protocols. Finally, we have shown a one-pot sequence describing C-H borylation/Cu-catalyzed homocoupling/Pd-catalyzed Suzuki coupling to obtain pi-extended arene frameworks.

A protocol of highly regio- and enantioselective copper-catalyzed hydroacylation of the non-terminal CC bond in 1,1-disubstituted terminal allenes with anhydrides has been developed. Both aromatic and aliphatic carboxylic anhydrides are applicable to the efficient construction of all carbon quarternary centers connected with a versatile C-C bond and a useful ketone functionality. The synthetic potentials of the enantioenriched products have also been demonstrated. Density functional theory (DFT) calculations were performed to explain the steric outcome of the products: the hydroacylation proceeds through a six-membered transition state and the ligand-substrate steric interactions account for the observed enantioselectivity although the chiral ligand is far away from the to-be-genetated chiral center.
