Tertiary α,Ï-diamines are selectively prepared in high yields by the reaction of α,Ï-diolefins with secondary amines, carbon monoxide and hydrogen in the presence of [Rh(cod)Cl]2 as a catalyst precursor. This one-pot synthesis proceeds via a hydroformylation-amine condensation-reduction sequence and leads to a mixture of n,n-, n,iso-, and iso,iso-products.
通过α,ω-二烯与二级胺、一氧化碳和氢气在[Rh(cod)Cl]2作为催化前体的存在下反应,可选择性地高产率制备三级α,ω-二胺。这种一步合成法经过羰基化-胺缩合-还原的连续步骤,生成n,n-、n,异-和异,异-产品的混合物。
