Preformed lithium enolates of ketones react with acyclic a,p-unsaturated ketones to give 1,5-diketones in good chemical yields. A strong correlation exists between enolate geometry and product stereochemistry; enolates having the z configuration provide anti addition products while E enolates usua

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
