Abstract

Abstract Reaction of 1H-cyclopropa [b] naphthalene (1a) or 1H-cyclopropa [b] anthracene (10a) with tris (acetonitrile) tricarbonylchromium affords cyclobutanaphthalenone and cyclobutaanthracenone 2 and 11, respectively. In contrast, the bis-silylated Cycloproparenes 1b and 10b undergo complexation at the terminal benzene ring and lead to the arene- tricarbonylchromium complexes 4b and 12, respectively. Desifylation of 4b to 4a is ...
