The thermolysis of a bis(pentacoordinate) silicon compound having two pentacoordinate silicon units at the 4- and 8-positions on the 1,5-bis(dimethylamino)naphthalene ring in the presence of diphenylacetylene affords a 1,6-dihydro-1,6-disilapyrene derivative. This reaction might proceed through a two-site silylene trapping with two acetylene molecules accompanied by an amino group migration from the
