Abstract

Heating silacyclobut-3-ene 2 at 250 °C afforded the trans-silacyclobut-3-ene 4, via the silylsubstituted cycloprop-2-ene 3. The photolysis of 4 gave a 1:1 mixture of 4 and the cis isomer 6, which was transformed into 4 at 250 °C, quantitatively. Preliminary results of the theoretical treatment for the isomerization of 2′ to 8′ are described.
