摘要

本研究报告采用了一种新颖高效的方法，通过三级丙炔胺与芳基硅氧烷的脱氨基偶联，在钯催化下高区域选择性地合成了三取代烯烃。使用 Et3N-3HF 对未活化的丙炔胺和芳基硅氧烷进行原位活化，然后进行交叉耦合，通过 C-N 键裂解促进 C-C 键的形成。该方法具有优异的官能团兼容性、高产率和易于获得的耦合伙伴。

Efficient synthesis of trisubstituted allenes via palladium-catalysed deaminative coupling of tertiary propargylamines with arylsiloxanes

A novel and efficient method for the palladium-catalysed and highly regioselective synthesis of trisubstituted allenes via deaminative coupling of tertiary propargylamines with arylsiloxanes is reported. Both unactivated propargylamines and arylsiloxanes were activated in situ using Et₃N·3HF, followed by cross-coupling to facilitate C–C bond formation through C–N bond cleavage. The method demonstrates exceptional functional group compatibility, high yields, and readily accessible coupling partners.
