A process is provided for the hydrogenation or asymmetric hydrogenation of dialkyl, alkylalkenyl and dialkenyl imines of formula (II) to provide amines of formula (III), wherein, (i) R1 and R2 are optionally substituted cyclic, linear or branched alkyl or alkenyl; R3 is a hydrogen atom, a hydroxy radical, optionally substituted C1 to C8 cyclic, linear or branched alkyl or alkenyl, optionally substituted aryl; or (ii) R1 is alkyl or alkenyl, R2 is alkyl or alkenyl and the two are linked together or with R3 to form one or more rings; using a catalytic system comprising a base and a ruthenium complex containing (1) a diamine and (2) a diphosphine ligand or monodentate phosphine ligands in hydrogenation and asymmetric hydrogenation processes.
提供一种用于二烷基、烷基烯基和二烯基亚胺(式II)的氢化或不对称氢化的过程,以提供式(III)的胺,其中,(i)R1和R2是可选取代的环、线性或支链烷基或烯基;R3是氢原子、羟基自由基、可选取代的C1至C8环、线性或支链烷基或烯基、可选取代的芳基;或(ii)R1是烷基或烯基,R2是烷基或烯基,并且两者与R3结合形成一个或多个环;使用催化体系,包括碱和含有(1)二胺和(2)二膦配体或单齿磷配体的钌配合物,在氢化和不对称氢化过程中。
