for the synthesis of isomerically pure δ-chloro-γ-vinylketones was developed on the basis of monoalkylation of β-ketoesters with the individual isomers of 1,3-dichloropropene and the subsequent decarbalkoxylation of the resulting chlorovinyl derivatives under optimized Krapcho decarboxylation conditions.

An efficient synthesis of a widely used fragrance, 2-[(2E)-hex-2-en-1-yl]cyclopentan-1-one, has been developed on the basis of iron-catalyzed cross-coupling of 2-[(2E)-3-chloroprop-2-en-1-yl]cyclopentan-1- one with propylmagnesium bromide.
