## Abstract Double nucleophilic addition reactions of dialkoxy ketenesilyl acetals proceeded with α,β‐unsaturated imines to give 1,4‐ and 1,2‐double addition products, and their subsequent transformations afforded multisubstituted pyrroles in good yields. Application of this procedure to the synthe

A variet-y of3-alkynyl perfluoroaikyi ketones were prepared by a trifluoroborane etherate mediated 1,4-addition reaction of ( I -alkynyl)diisopropoxyboranes to a,p-unsaturated ketones substituted by a perfltloroalkyl group. The undesired side reaction, such as 1,2-addition of alkynyl groups, could b
