title: Cyclization/hydrosilylation of functionalized diynes catalyzed by a cationic platinum phenanthroline complex.
abstract: [figure: see text] A 1:1 mixture of the platinum phenanthroline complex (phen)PtMe2 and B(C6F5)3 catalyzed the cyclization/hydrosilylation of functionalized 1,6- and 1,7-diynes to form silylated 1,2-dialkylidenecycloalkanes in good yield and with high Z-selectivity.
