Title: The dimer of unsubstituted silole

Abstract

Gas-phase flow pyrolysis of 1-(trimethylsilyl)-1-silacyclopent-3-ene and 1-methoxy-1-(trimethylsilyl)-1-silacyclopent-3-ene leads to the formation of the dimer of silole, 3,8-disila-3a, 4,7,7a-tetrahydro-4,7-methano-1H-indene. Attempts to isolate or trap the silole monomer by means other than self-reaction have failed. It is suggested that the initially formed intermediate silylene, 1-silacyclopent-3-enylidene, undergoes rearrangement to silole and that silole is not very reactive in 2 + 4 cycloadditions, but does undergo dimerization. 19 refs., 1 fig.
