In ionic liquid [bmim]BF4, SnCl2·2H2O acts as an inexpensive and efficient metal salt for carbonyl allylation. By applying ionic liquid, some previously reported serious operational problems associated with the SnCl2-mediated allylation reaction are avoided. Furthermore, ketones, which are less reactive than aldehydes, can also be allylated in high yields with this system.
在离子液体[bmim] BF 4中,SnCl 2 ·2H 2 O作为一种廉价而有效的羰基烯丙基化金属盐。通过施加离子液体,避免了一些先前报道的与SnCl 2介导的烯丙基化反应相关的严重操作问题。此外,与该醛相比反应性较弱的酮也可以通过该系统以高收率烯丙基化。
