✦ Synopsis

Telomerization of 1,1,3,3-tetramethyl-1,3-disilacyclobutane with hydrosilanes is facilitated by UV irradiation in the presence of Pt(acac)2. When olefin is also present, photoactivated hydrosilylation competes with telomerization. The dependence of product distribution on the reactivity of the hydrosilanes and the olefins was studied.
