摘要:

AbstractA variety of 3‐alkynyl perfluoroalkyl ketones were prepared by a trifluoroborane etherate mediated 1,4‐addition reaction of (l‐alkynyl)diisopropoxyboranes to α,β‐unsaturated ketones substituted by a perfluoroalkyl group. The undesired side reaction, such as 1,2‐addition of alkynyl groups, could be avoided completely and the products were obtained in
