Abstract

TpRuPPh(3)(CH(3)CN)(2)PF(6) catalyzed the transformation of various 3-benzyl but-1-ynyl ethers into dienes and benzaldehyde at a catalyst loading of 5 mol %. This process represents an atypical pattern of transfer hydrogenation. This catalytic reaction can be applied to various derivatives of 2-ethynyl tetrahydrofurans and pyrans to cleave their ether rings and gives diene and tethered aldehyde functionalities, respectively.

摘要

TpRuPPh(3)(CH(3)CN)(2)PF(6)在5 mol%的催化剂负载量下催化各种3-苄基丁-1-炔基醚转化为二烯和苯甲醛。该过程代表了一种非典型的转移氢化模式。这种催化反应可应用于2-乙炔基四氢呋喃和吡喃的各种衍生物，以裂解它们的醚环，并分别生成二烯和连接的醛官能团。
