A novel nanohybrid structure was synthesized by assembling gold nanoparticles on polymerized polydiacetylene nanotubes. Combination of the nanohybrid with gallacetophenone afforded an efficient cooperative co-catalytic system for the oxidative coupling of primary amines into imines. The system is highly efficient and sustainable as it operates in high yields using minimal amounts of the metal and the quinone, under ambient atmosphere, at room temperature, in water, and is easily recycled.

Two new compounds of β-amino alcohol are obtained using (R) - (+) - α-methylbenzylamine as starting material which is converted into two amines. Each of these compounds reacted in excess with a 1: 1 mixture of cis and trans-limonene oxide in the presence of water as a catalyst. The products obtained show that β-amino alcohol derived from trans-limonene oxide is obtained and unreacted cis-limonene oxide from the reaction mixture as well as the amine is attained. Whereas the addition of the synthesized carbamate of the same primary amine over the 1: 1 mixture of cis and trans -limonene oxide in the presence of water results in the hydrolysis product and the recovery of unreacted trans-limonene oxide.

Vanadium(IV) tetraphenylporphyrin dichloride and chromium(III) tetraphenylporphyrin chloride have been developed as catalysts for the acceptorless dehydrogenation of alcohols. The catalysts have been applied to the direct synthesis of imines in overall good yields from a variety of alcohols and amines. The transformations are proposed to proceed by metal?ligand bifunctional pathways with an outer-sphere transfer of two hydrogen atoms from the alcohol to the metal porphyrin complexes. The results show that vanadium and chromium catalysts can also be employed for the dehydrogenation of alcohols with the release of hydrogen gas, and they may represent valuable alternatives to other catalysts based on Earth-abundant metals.
