Here, we explore the GO-catalyzed cross-dehydrogenative coupling of oxindoles with arenes and thiophenols for the rapid synthesis of 3-aryloxindoles and 3-sulfenylated oxindoles. Control experiments and small-molecule mimicking studies reveal that the acidic nature and quinone-type functionalities of GO are synergistically utilized for the coupling reaction. The reaction proceeds under simple and mild reaction conditions, exhibits good functional group tolerance, and can be easily scaled up to the gram level.

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 metal-free aromatic electrophilic substitution reaction using nitrosoarenes as the electrophile in 1,1,1,3,3,3-hexafluoroisopropanol (HFIP) is reported. HFIP activates nitrosoarene towards the electrophilic C-H amination followed by a concomitant N-O bond cleavage to deliver diarylamines without requiring any extra reagent or further treatment. The dual electrophilic nature of nitrosoarene permits a switchover of selectivity to C-H oxygenation furnishing dearomatizedp-iminoquinones following a unique mechanistic rationale of two consecutive [2,3] sigmatropic rearrangement in nitroso-chemistry.

Work previously published by our group described novel methodology for the synthesis of xanthones and related products from phenolic benzophenones in a reaction mediated by ceric ammonium sulfate (CAS). In this paper we further explore this novel reaction by subjecting an additional set of phenolic benzophenones to CAS to afford a range of compounds, including xanthones, 9H-xanthen-2,9(4aH)-diones, 3H-spiro[benzofuran-2,1′-cyclohexa[2,5]-diene]-3,4′-diones, and biaryl compounds. A comparison of these reactions with the more commonly used oxidant ceric ammonium nitrate (CAN) was also conducted. Based on these results, greater insight into the reaction mechanism has been gained. In addition, the conversion of the synthesized xanthen-2,9(4aH)-diones to xanthones by treatment with sodium dithionite is described.

An efficient and facile method has been developed for the synthesis of alkyl bromides from various alcohols under mild conditions using a triphenylphosphine (PPh3)/1,2-dibromotetrachloroethane (DBTCE) complex in excellent yields and very short time (5 min). This method can also be applied for the transformation of chiral alcohols to their corresponding bromides in very high enantiomeric excess. The PPh3/DBTCE complex is also successfully applied to ring-opening reactions of cyclic ethers in mild conditions. Esterification, amidation, and formation of acid anhydrides under very mild experimental conditions are also successfully accomplished by following a modification of the Appel reaction protocol in this work.

The biaryl motif is a building block in many drugs, agrochemicals, and materials, and as such it is highly desirable as a synthesis target. The state-of-the-art process for biaryl synthesis from ubiquitous carboxylic acids is decarboxylative cross-coupling involving loss of carbon dioxide (CO2). However, the scope of these methods is severely limited, mainly due to specific substitution required to promote decarboxylation. The present report implements a decarbonylative version with loss of carbon monoxide (CO) that enables to directly engage carboxylic acids in a Suzuki-Miyaura cross-coupling to produce biaryls as a general method with high cross-coupling selectivity using a well-defined Pd(0)/(II) catalytic cycle. This protocol shows a remarkably broad scope (>80 examples) and is performed in the absence of exogenous inorganic bases. In a broader context, the approach shows promise for routine applications in the synthesis of biaryls by carefully controlled decarbonylation of prevalent carboxylic acids.

A gas sensor has been fabricated by depositing the thin film of Functionalized Graphene Oxide (GO) using Langmuir Blodget (LB) technique on SiO2/Si wafers. Aluminum (Al) contacts were deposited using thermal evaporation technique for measuring the resistance of fabricated thin film. Three different concentrations (15 mM, 50 mM, 75 mM) of Meta Toluic acid (MTA) have 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 both GO and functionalized GO to study the surface morphology. Gas sensing behavior of functionalized GO has been investigated using two probe resistance measurement method for different concentration of ammonia gas. Sensor response was studied for ammonia concentration varied from 100 to 2000 ppm. Highest response obtained at 100 ppm concentration was found to be similar to 12.2% for sample TG(75). Higher concentration of MTA (up to a critical value) in GO leads to higher response of ammonia gas. This enhanced gas response has been due to the increased ester formation reaction at the surface of sensing film, which eventually leads to more interaction with NH3 gas molecules. In addition, defects and carbon vacancy in functionalized GO also acts as the trapping sites for gas molecules being sensed. The selectivity of the sensor has been investigated in different environment and sensor was found to be very selective towards ammonia gas. For stability investigation of the fabricated sensor, the sensor response has been recorded for 45 days.
