The complex [Rh(ItBu)2HCl] has been shown to be an active catalyst in the hydrosilylation of carbonyl and imine complexes. This reactivity, combined with the previously reported H/D exchange catalyzed by these complexes allows for a one pot, two step reaction using a single catalyst for both H/D exchange and hydrosilylation. Using triethylsilane, [Rh(ItBu)2Cl] catalyst, and D2 gas, deuterated silyl-ethers can be synthesized in an atom-economical, solvent-free reaction.
复杂物[Rh(ItBu)2HCl]已被证明在羰基和亚胺络合物的氢硅烷化反应中是一种活跃的催化剂。这种反应性结合先前报道的这些络合物催化的氘/氢交换,使得使用单一催化剂进行一锅两步反应成为可能,用于氘/氢交换和氢硅烷化。利用三乙基硅烷、[Rh(ItBu)2Cl]催化剂和D2气体,可以以原子经济、无溶剂的反应合成氘代硅醚。
