A conjugated spirocyclic polymer was synthesized via the cyclopolymerization of 1,1-dipropargyl-1silacyclohexane with various transition metal catalysts. The monomer, 1,1-dipropargyl-1-silacyclohexane was synthesized by Grignard reaction of 1,1-dichloro-1-silacyclohexane with propargyl magnesium bromide. This polymerization proceeded well to give the corresponding poly(1,1-dipropargyl-1-silacyclohexane). The catalytic activity of WCl 6 was found to be similar with that of MoCl 5 .
