摘要

摘要在可见光诱导（460 nm）催化下，开发了一种在 N,N-二甲基乙酰胺中用 Pd(PPh3)4/[Bu4N]I 体系与叔烷基氯化物和烷基溴化物对（苯）恶唑进行选择性 C(2)H 烷基化的方法。四烷基铵盐对反应有显著的促进作用，这似乎是基于催化体系中纳米级钯物种的稳定。

C(2)H-Alkylation of (Benz)oxazoles with Tertiary Alkyl Chlorides and Bromides under Photoinduced Palladium Catalysis

A method has been developed for the selective C(2)H alkylation of (benz)oxazoles with tertiary alkyl chlorides and alkyl bromides under visible light-induced (460 nm) catalysis with the Pd(PPh₃)₄/[Bu₄N]I system in N,N-dimethylacetamide. The tetraalkylammonium salt has a significant promoting effect on the reaction, which seems to be based on the stabilization of nanosized palladium species in the catalytic system.
