Abstract

Synthesis of indeno(5',6'-6,7)tropone (IX) and indeno(5',6')tropylium (X) fluoroborate are described. The tropone shows no tendency to tautomerize to XXI, a derivative of cyclohept(f]indene. In an attempt to generate cyclohept[f]indene, the action of triethylamine on the tropylium (X) fluoroborate was investigated, but without success.
