Abstract

The synthesis of 9, 10-dibenzyl-9, 10-diphenyl-9, 10-dihydro-9-sila-anthracene (8), and of some similarly substituted 9, 10-dihydro-9-silaanthracenes is reported. Compound 8 was prepared with the aim of converting it by Flash Vacuum Thermolysis (FVT) into 9, 10- diphenyl-9-silaanthracene (4), with 1, 2-diphenylethane (5) as the expected byproduct. At lower temperatures, a surprisingly stable, dark green organic radical was formed, which ...
