摘要：

Peralkylated 3,4-bis(alkylidene)- 1,2-disilacyclobutanes prepared by convenient synthetic route were quantitatively converted to 3,4,7,8-tetrakis(alkylidene)-1,2,5,6-tetrasilacyclooctane (twist and chair 1: 1 mixture) by Pd-catalyzed reaction. In the presence of unsaturated compounds, this disilane metathesis reaction was inhibited to give double silylation products. The reaction pathways are highly dependent upon electronic factors of unsaturated compounds and the catalyst.
