Synthesis of 4<i>H</i>-benz[<i>de</i>]anthracen-4-ones via 1,2-addition of metal acetylides to benzanthrone

Abstract

<p>Easy and facile syntheses of the 4<i>H</i>-benz[<i>de</i>]anthracen-4-one derivatives were achieved by the reaction of benzanthrone and lithium acetylides, followed by the treatment with silica gel in CHCl₃.</p
