Treatment of allenes with Ph3SnH or Ph3GeH in the presence of Pd(PPh3)4 catalyst provides the corresponding allylic stannanes or allylic germanes in good yields. Et3B induced radical addition of Ph3SnH or Ph3GeH to allenes are also described.
在 Pd(PPh3)4 催化剂存在下,用 Ph3SnH 或 Ph3GeH 处理烯烃,可以得到相应的烯丙基
锡烷或烯丙基
锗,产率很高。此外,还介绍了在 Et3B 诱导下 Ph3SnH 或 Ph3GeH 与烯烃的自由基加成。
