A remarkably simple entry to unsymmetrical diarylmethanes has been developed that relies on an in situ organozinc-mediated, palladium-catalyzed cross-coupling. Thus, by mixing a benzyl and aryl halide together in the presence of Zn metal and a Pd catalyst, diarylmethanes are formed at room temperature without assistance by a surfactant; hence, "on water".
已经开发了一种非常简单的不对称二芳基甲烷入口,它依赖于原位有机锌介导的钯催化交叉偶联。因此,通过在 Zn 金属和 Pd 催化剂存在下将苄基和芳基卤化物混合在一起,在室温下形成二芳基甲烷,无需表面活性剂的帮助;因此,“在水上”。
