A metal-coordination-driven self-assembly using the predesigned building block has been developed. Herein, the catalytic active NHC–Cu(I) units were introduced into the terpyridine metal coordination polymers. The self-assembled architecture, as a heterog

Synthesis of terminal allenes via a copper-catalyzed decarboxylative coupling reaction was developed. Aryl alkynyl carboxylic acid, paraformaldehyde, and dicyclohexylamine were reacted with CuI (20 mol %) in diglyme at 100°C for 2 h to produce the terminal allene in moderate to good yields. The method showed good functional group tolerance.

Fe-doped mesoporous metal oxides (Fe/MO2, M = Si and Ti) were synthesized with particle size in the range of 10–15 nm via modified sol–gel method. The Fe modified SiO2 and TiO2 have proved to be very efficient catalysts in three-component coupling of aldehydes, alkynes and amines for the solvent-free synthesis of proargylamines. Among the two Fe-doped metal oxide catalysts, Fe/TiO2 gives 94% propargylamine yield at 245 W microwave power for few minutes under solvent free condition and found to be a better catalyst. With a Fe/TiO2 heterogeneous catalyst and in the absence of solvent, the proposed process for propargylamine synthesis is green and environmentally benign protocol.
