Abstract
Carbanions derived from N-(p-nitrobenzyl)-dihydrosilaazaanthracene condense with acetylenedicarboxylic ester to form substituted silanaphthoindolizines and silaazaaceanthrenes. The analogous salt of the 9-oxo derivative gave the oxo substituted silanaphthoindolizine. The compounds obtained were subjected to reduction, hydrolysis, and opening of the sila-ring.
