Conclusions 1. Oxidative addition of acetone to butadiene in the presence of the system Mn(OAc)3-Cu(OAc)2 has afforded 5-acetoxy-6-hepten-2-one, three isomeric 1-methyl-3,7-divinyl-2,8-dioxa-cis-bicyclo[3.3.0]octanes with the vinyl groups with the exo,exo, exo,endo, and endo,endo dispositions, and three diastereoisomeric 2,7-divinyl-1,6-dioxaspiro[4.4]nonanes. 2. Oxidative addition of acetopropyl alcohol and dihydrosylvan to butadiene results in the formation in both cases of identical mixtures of exo- and endo-1-methyl-3-vinyl-2,8-dioxa-cis-bicyclo[3.3.0]octanes and diastereoisomeric 2-vinyl-1,6-dioxaspiro[4.4]nonanes, indicating that the reaction proceeds via the same intermediate, probably a complex of Mn(III) with the ketoalcohol.
