Allenyl carbinol ester 3 isomerizes to an E,Z mixture of the corresponding diene 2 in the presence of gold catalyst 4, but the resulting mixture yields monofluoroalkyl α,β-unsaturated ketone 1 with exclusive E selectivity and in high yields after reaction with Selectfluor.
在金催化剂4的存在下,烯丙基甲醇酯3异构化为相应的二烯2的E,Z混合物,但与Selectfluor反应后,所得混合物可生成具有唯一E选择性的单氟烷基α,β-不饱和酮1。
