The obvious extensions to the photochemistry of silylthiophenes and silylpyrroles have now been investigated and are reported here. We find that silyl substitution has no apparent positive effect on the photochemistry of thiophenes. Irradiation of either 2-(trimethylsilyl)- thiophene or 2, 5-bis (trimethylsilyl) thiophene in degassed pentane yields only intractable polymer. In contrast to these unremarkable results, photolysis of silyl-substituted pyrroles ...
