A wide range of arylated alkynes are synthesized from the corresponding aryl halides and terminal alkynes through Sonogashira type cross-coupling reactions through C(aryl)-C bond formation in the presence of a catalytic amount of N,N′-dibenzyl BINAM-CuI complex under mild reaction conditions.

A general method to synthesize substituted butenolides from hydroxymethylcyclopropenones is reported. Functionalized cyclopropenones undergo ring-opening reactions with catalytic amounts of phosphine, forming reactive ketene ylides. These intermediates can be trapped by pendant hydroxy groups to afford target butenolide scaffolds. The reaction proceeds efficiently in diverse solvents and with low catalyst loadings. Importantly, the cyclization is tolerant of a broad range of functional groups, yielding a variety of α- and γ-substituted butenolides.

Bispropargyl sulfones equipped with aromatic rings of dissimilar nature were synthesized. Under basic conditions, these sulfones isomerized to the bisallenic sulfones, creating a competitive scenario between two alternate Garratt-Braverman (GB) cyclizatio
Copper(I)-catalyzed Caryl-Calkynyl bond formation of aryl iodides with terminal alkynes
Thakur,Sekar
scheme or table, p. 2785 - 2789 (2010/01/21)
A wide range of internal alkynes are synthesized from the corresponding aryl iodides and terminal alkynes by Sonogashira-type cross-coupling reactions through Caryl-Calkynyl bond formation in the presence of a catalytic amount of readily available DBU-CuBr complex under mild reaction conditions.
