摘要

Abstract o-(Phenylethynyl) phenyllithiums, generated by treatment of o-(phenylethynyl) bromobenzenes with tBuLi, were quenched with N, N-dimethylcarboamides to afford various 2-phenylindenone derivatives in moderate to good yields upon acidic workup. The choice of lithiation reagents was critical. When n-butyllithium was used the yields were reduced. The N-alkyl groups in the carboamides were also important: quenching with N, N- ...
