Cycloaddition of CO2 to epoxides using di-nuclear transition metal complexes as catalysts

Studies on the reaction and conversion of CO2 to valuable products have made much progress in recent years, and the search for efficient catalysts is also expanding. Cycloaddition of CO2 to epoxides was carried out selectively using di-nuclear CuII, CoII and NiII complexes (C1, C2 and C3, respectively) as catalysts. The complexes were synthesized in good yield and characterized by various physical and spectroscopic methods. In all complexes the ligand L acted as a bidentate NO donor favouring distorted octahedral, tetrahedral or square planar geometry for C1, C2 and C3, respectively. Complex C2 in the presence of n-Bu4NI as a cocatalyst showed the highest activity among the reported complexes in the cycloaddition reaction.

Cascade Process for Direct Transformation of Aldehydes (RCHO) to Nitriles (RCN) Using Inorganic Reagents NH2OH/Na2CO3/SO2F2 in DMSO

A simple, mild, and practical process for direct conversion of aldehydes to nitriles was developed feathering a wide substrate scope and great functional group tolerability (52 examples, over 90% yield in most cases) using inorganic reagents (NH2OH/Na2CO3/SO2F2) in DMSO. This method allows for transformations of readily available, inexpensive, and abundant aldehydes to highly valuable nitriles in a pot, atom, and step-economical manner without transition metals. This protocol will serve as a robust tool for the installation of cyano-moieties to complicated molecules.

Synthesis and photo-alignment properties of novel polymer with terephthalaldehyde

To improve irradiation time and the effectiveness photo-alignment, dual decomposition mechanisms including photo and thermal were investigated. For more aggressive photo-decomposition of the polymer, the photoreactions employing triplet mechanism and the
