Summary: The catalytic addition of water to unsaturated C-C or C-N p bonds is an important and environmentally sustainable method for forming C-O bonds. Traditional acid-catalyzed hydration requires strong acids or toxic mercury salts, limiting its practical applications and posing safety and environmental concerns. Transition-metal-catalyzed hydration with NHC ligands has gained significant attention and has achieved major progress. This review provides a comprehensive overview of hydration reactions catalyzed by transition metal-NHC complexes and their applications in catalytic hydration.

Summary: We report the Pd-catalyzed Suzuki-Miyaura cross-coupling of aliphatic amides. The selective N-C(O) cleavage to form C-C bonds from aliphatic amides has been a major challenge in Pd catalysis. This study addresses this longstanding problem by using N,N-pym/Boc amides as reagents for cross-coupling and steric tuning of Pd(II)-NHC catalysts. The method is effective for various degrees of aliphatic amide derivatives and the catalyst system is user-friendly. Mechanistic studies support the twist of amide bond and external n(N) -> pi(C=O/Ar)* delocalization as a unified enabling feature of N,N-pym/Boc amides in selective N-C(O) bond activation. This method provides a rare example of Pd-NHC-catalyzed cross-coupling of aliphatic acyl amide electrophiles.

Summary: This article highlights the recent advances in the N-heterocyclic carbene (NHC)-organocatalyzed generation of azolium enolate intermediates and their subsequent interception with electrophiles. The NHC-bound azolium intermediates are generated by adding NHCs to suitably substituted aldehydes, acid derivatives, or ketenes. A wide range of coupling partners can intercept the azolium enolates to form [2+n] cycloadducts (n=2,3,4) and various alpha-functionalized compounds. Enantioselective synthesis of the target compounds is achieved with chiral NHCs.

Summary: Long-standing research efforts have led to the widespread use of organic field-effect transistors (OFETs) in next-generation technologies, but environmental and operational stability remains a major challenge in commercializing OFETs. In this study, the impact of ambient air on the performance of p-type polymer field-effect transistors was demonstrated. It was found that the degradation of device stability is primarily caused by the channel resistance rather than the contact resistance. Fourier transform infrared (FTIR) analysis revealed that water and oxygen interact with the polymer chain and disrupt its conjugation, resulting in degraded device performance after prolonged exposure to ambient air. These findings are crucial for addressing the environmental instability of organic devices.

Summary: Our research focuses on the properties of N-heterocyclic carbene salts and their silver acetate-based complexes, including their structure, biology, and electronics. We synthesized compounds after conducting theoretical calculations, using B3LYP functional with 6-31++G and LanL2DZ basis sets for salts and complexes, respectively. Non-covalent interactions were evaluated, and electronic parameters, HOMO and LUMO energies, were calculated to assess their biological potential. Density of states analysis was conducted to examine electronic densities. Compound 3, with an energy gap of 0.121 eV, was considered the best among all compounds. Due to reasonable HOMO-LUMO energy gaps, all eight compounds were deemed feasible for synthesis and showed strong biological potentials. Characterization of compounds was done using FT-IR and NMR spectroscopy.

Summary: MnO2 is an attractive material with high specific capacitance, excellent electrochemical activity, thermal and chemical stability, environmental benignity, and broad potential window. However, its poor electrical conductivity limits its performance in supercapacitor applications. The present study compares the effects of various carbon nanomaterials on the supercapacitive performance of MnO2 electrodes. The results show that MnO2-CNTs composite electrodes exhibit significantly improved specific capacitance and charge retention compared to pure MnO2 and previously reported MnO2/CNTs composite electrodes.
