dirty! Microwave heating was found to have a significant effect on the Ru‐catalyzed hydrovinylations of alkynes. A broad range of different terminal alkynes were coupled to methyl acrylate within just 30 min in good to excellent yields (see scheme). This new protocol was transferred to the hydrovinylation of enynes as novel coupling partners in CH‐activation chemistry giving different 1,3,5‐trienes
快速,但不脏!发现微波加热对Ru催化的炔烃氢化乙烯基化有显着影响。在短短30分钟之内即可将各种不同的末端炔烃与丙烯酸甲酯偶联,获得良好至优异的收率(参见方案)。这个新的协议转移到烯炔在C新颖偶联伴侣的hydrovinylation 给予不同的1,3,5-三烯作为唯一的产品H-激活化学。
