PREPARATION AND REACTIONS OF ANTHRONE AND XANTHENE-TRIPHENYLPHOSPHONIUM SALTS. A FACILE AND EFFICIENT APPROACH TO ALKYLATION AND ALKENYLATION OF CYCLES AND HETEROCYCLES

PREPARATION AND REACTIONS OF ANTHRONE AND XANTHENE-TRIPHENYLPHOSPHONIUM SALTS. A FACILE AND EFFICIENT APPROACH TO ALKYLATION AND ALKENYLATION OF CYCLES AND HETEROCYCLES

Triphenylphosphonium salts (3) of 10,10-dibromoanthrone (1a) and 9,9-dichloroxanthene (1b) were prepared and generalized reactions for the salts (e.g. Wittig reaction, hydrolysis and thermolysis) were suggested and illustrated using the aforementioned species.
