Several masked disilene monomers, i.e. 1-phenyl-7,8-disilabicyclo[2.2.2]octa-2,5-dienes, were prepared regioselectively by the reaction of unsymmetrically substituted dichlorodisilanes with biphenyl radical anions. These monomers gave polysilylenes with highly ordered structures. Important information on the tacticity of polysilylenes was obtained by detailed analysis of n.m.r, spectra. The mechanism of monomer formation as well as the polymerization mechanism are discussed
