Abstract
In the presence of CuCN, reaction of γ, γ-dialkoxyallylic zirconium species 1 with acyl chloride or allylic phosphates proceeded at the α-position of 1 to give alkanoates 3 after aqueous work-up. The ketene dialkylacetal moiety in the coupling products 2 can be used for further bond forming reaction with electrophiles such as nitrosobenzene, nitrostyrene or trichloroacetylisocyanate.
