Abstract 10-Aryl-9-arsaanthracenes (3b, c, d) were conveniently synthesized by flash vacuum pyrolysis at∼ 500 of 10-mono-and di-substituted 9-aryl-9, 10-dihydro-9- arsaanthracenes (11a-f). The yield of 10-aryl-9-arsaanthracenes is found to depend upon the substituents at C (10). The occurrence of radical intermediates is discussed briefly.
