| Abstract: | Thermolysis of 1,1-dimethyl-2-phenyl-3-trimethylsilyl-1-silacyclopropene in the presence or absence of an alkyne such as diphenylacetylene or ethyl-dimethylsilylphenylacetylene gave a mixture of 1,1,4,4-tetramethyl-2,5-diphenyl-3,6-bis(trimethylsilyl- and 1,1,4,4-tetramethyl-2,6-diphenyl-3,5-bis(trimethylsilyl)-1,4-disilacyclohexa-2,5-diene in high yield. The formation of the 1,4-disilacyclohexa-2,5-diene system can be best rationalized in terms of a mechanism involving direct dimerization of the 1-silacyclopropene. |
