to catalyze the dehydrogenative coupling of certain amines and hydrosilanes at elevated temperatures. At higher temperature, the dehydrogenation pathway competes with cleavage of the C−N bond and defunctionalization is obtained. This can be turned into a useful methodology for the transition‐metal‐free reductive deamination of a broad range of amines as well as heterocumulenes such as an isocyanate and
已知强硼路易斯酸三(五氟苯基)硼烷B(C 6 F 5 ) 3在高温下催化某些胺和氢硅烷的脱氢偶联。在较高温度下,脱氢途径与CN键的断裂竞争并获得去官能化。这可以成为一种有用的方法,用于多种胺以及异氰酸酯和异硫氰酸酯等杂积烯的无过渡金属还原脱氨。
