Abstract Soft reaction conditions, particularly important in total synthesis, have dragged many researchers into the field of silylated organic compounds. Hereby, we describe a new copper-catalyzed vinylsilane transformation. Various vinylsilanes were allylated by using a copper (I) salt, and this led to the formation of polysubstituted 1, 4-dienes bearing sensitive moieties such as halogens, ketones, and aldehydes.
