A palladium-catalyzed N-acylation of tertiary amines by carboxylic acids was achieved through C-N cleavage. This reaction showed a wide substrate scope. Both aromatic and aliphatic acids served well as the acylating reagents and coupled with tertiary amines to produce the corresponding amides in good to excellent yields. With the strategy, bioactive carboxylic acids were also efficiently modified, highlighting the synthetic value of the process in organic synthesis.

Azetidines are valuable motifs that readily access under explored chemical space for drug discovery. 3,3-Diarylazetidines are prepared in high yield from N-Cbz azetidinols in a calcium(II)-catalyzed Friedel-Crafts alkylation of (hetero)aromatics and phenols, including complex phenols such as beta-estradiol. Electron poor phenols undergo O-alkylation. The product azetidines can be derivatized to drug-like compounds through the azetidine nitrogen and the aromatic groups. The N-Cbz group is crucial to reactivity by providing stabilization of an intermediate carbocation on the four-membered ring.

An article Room temperature ammonia gas sensor using ester functionalization of graphene oxide WOS:000477594800001 published article about ADSORPTION; TRANSPARENT; SENSITIVITY; FILMS in [Kumar, Ravi; Kumar, Anil; Singh, Rakesh; Kashyap, Rajesh; Kumar, Dinesh; Kumar, Mukesh] Kurukshetra Univ, Elect Sci Dept, Kurukshetra 136119, Haryana, India; [Kumar, Rajiv] Kurukshetra Univ, Dept Chem, Kurukshetra 136119, Haryana, India; [Kumar, Dinesh] YMCA Univ Sci & Technol, Faridabad, India in 2019.0, Cited 42.0. The Name is 3-Methylbenzoic acid. Through research, I have a further understanding and discovery of 99-04-7. Formula: C8H8O2

A room temperature ammonia gas sensor has been fabricated by depositing the thin film of Functionalized Graphene Oxide (GO) using Langmuir Blodgett (LB) technique on SiO2/Si wafers. Thermal evaporation technique was used for deposition of aluminum (Al) contacts for measuring the resistance of fabricated thin film. Different concentration of Meta Toluic acid (15 mM, 50 mM, 75 mM) has been used for functionalization of GO. X-Ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy were used to characterize the Graphene Oxide (GO) after functionalization. Also, Scanning Electron Microscopy (SEM) was carried out for bothGO and functionalized GO. Gas sensing behavior of functionalized GO has been investigated for different concentration of ammonia gas. Sensor response was studied for low concentration (100 ppm) of ammonia gas. Highest response at 100 ppm concentration was found to be similar to 12%. Higher concentration of MTA in GO leads to higher response of ammonia gas. This enhanced gas response is attributed to the enhanced ester formation reaction at the surface of sensing film, and more defects and carbon vacancy in functionalized GO, which eventually leads to more interaction with NH3 gas molecules.

Precise control over the morphology and size of coordination polymers (CPs) is crucial for extending these inorganic-organic materials to many advanced applications, in particular for heterogeneous catalysis. In this work, two Zn-based CPs, {[Zn-3(idbt)(2)(4,4 ‘-dmbpy)(2)]center dot H2O}(n) (1) and {[Zn-3(idbt)(2)(H2O)(3)]center dot H2O}(n) (2) (H(3)idbt = 5,5 ‘-(1H-imidazole-4,5-diyl)-bis-(2H-tetrazole), 4,4 ‘-dmbpy = 4,4 ”-dimethyl-2,2 ‘-bipyridine), were synthesized through solvothermal reactions. The morphologies and particle sizes of 1 and 2 could be controlled from large scale to nanoscale by regulating the amount of poly(vinyl alcohol) (PVA). Furthermore, for the conversion reactions of nitromethylbenzenes into benzoic acids, the catalytic properties of nanoscale 1 and 2 were much more efficient than those of large size of 1 and 2, because of the benefit of readily accessible active sites in the nanoscale sized particles, which provide a tunable and functionalizable platform for the conversion reaction by minimizing the diffusion distance but do little for the selectivity.

An article Organocatalytic Desymmetrisation of Fittig’s Lactones: Deuterium as a Reporter Tag for Hidden Racemisation WOS:000459926800025 published article about ACID CATALYZED DESYMMETRIZATION; MICHAEL ADDITION; BISLACTONES; DERIVATIVES; BILOBALIDE; ANHYDRIDE; MECHANISM; MALONATE in [Spranitz, Peter; Soregi, Petra; Botlik, Bence Bela; Berta, Mate; Soos, Tibor] Res Ctr Nat Sci, Inst Organ Chem, Magyar Tudosok Korutja 2A, H-1117 Budapest, Hungary in 2019, Cited 40.

Highly enantioselective desymmetrisation of Fittig’s lactones with alcohols is promoted by bifunctional cinchona squaramides. The reactions were carried out with monodeuterated methanol to detect possible hidden racemisation of the stereogenic centre. Current evidence suggests that racemisation was not a relevant process for most substrates; partial erosion of enantioselectivity was only detected with ortho-substituted aryl derivates. The resultant glutaric acid derivatives possess a scaffold that is common in natural products and the compounds are also useful chiral building blocks for further synthetic endeavours.

The antiausterity natural product (+/-)-uvaridacol L was synthesized for the first time in seven steps from myo-inositol. The key reaction of this synthesis, axial selective dibenzoylation of myo-inositol orthoformate, was achieved using a catalytic amount of tetrabutylammonium fluoride (TBAF). The preferential cytotoxicity of racemic uvaridacol L against cancer cell lines able to adapt to nutrient deprivation was also evaluated under nutrient deprived conditions. Morphological evaluation was also carried out.

Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

Herein, we present a nickel-catalyzed three-component reductive alkylacylation of electron-deficient activated alkenes with tertiary alkyl bromides and acid anhydrides. This method enables the efficient preparation of a variety of ketones with broad substrate scope and high functionality tolerance starting from simple precursors. On the basis of the preliminary mechanistic investigations, a catalytic cycle involving the synergistic interaction of nickel, zinc, and MgCl2 is proposed as the major reaction pathway.
