A novel synthesis of 10‐aryl‐9‐arsaanthracenes

Abstract

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.
