Now directly feasible: The silicon atom in allenylsilanes enabled their reaction with two equivalents of benzynes to generate (α‐phenanthrenyl)vinylsilanes in good to excellent yields through an unprecedented [2+2+2] pathway (see scheme).
现在直接可行:
烯丙基
硅烷中的
硅原子能够使其与两当量的
苯炔反应,以前所未有的[2 + 2 + 2]途径生成(α-
菲基)
乙烯基硅烷,收率高至优异(参见方案)。
