Synthesis of primary alcohols from terminal alkenes is an important process in both bulk and fine chemical syntheses. Herein, a homogeneous Pd‐complex‐catalyzed transformation of terminal alkenes into primary allylic alcohols, by using 5 mol % [Pd(PPh3)4] as a catalyst, and H2O, CO2, and quinone derivatives as reagents, is reported. When alcohols were used instead of H2O, allylic ethers were obtained
从末端烯烃合成伯醇在本体和精细化学合成中都是重要的过程。本文中,通过使用5 mol%[Pd(PPh 3)4 ]作为催化剂,并使用H 2 O,CO 2和醌衍生物作为试剂,将末端烯烃均相的Pd络合物均匀转化为伯烯丙基醇。报告。当使用醇代替H 2 O时,获得了烯丙基醚。拟议的机制包括在π-烯丙基Pd中间体的受阻较弱的末端位置添加氧亲核试剂。
