A new mode of carbon-carbon bond formation via electrophilic activation a C-H has been developed in the context copper-catalyzed anti-selective silylative cyclization benzylacetylenes with silylboronates for synthesis 2-silyl-1H-indenes. The reaction proceeds high regioselectivity various substituted benzylacetylenes, and resulting products could be further functionalized. arene that undergoes acts as an electrophile release hydride under redox neutral conditions, mechanism was probed by deuterium-labeling experiments density functional theory calculations.

A palladium-catalyzed (3 + 2) annulation of 2-methylbenzoic acid with maleimide using Ac-Leu-OH as a powerful ligand has been reported. Through site-selective γ-C(sp3)–H olefination reaction and sequential decarboxylative cross-coupling reaction, five-membered cyclic ring was obtained the final product. This novel features great site selectivity reactivity to generate various products in moderate good yields.
