In contrast to organocuprate conjugate addition and standard methods for conjugate reduction, use of the stable copper(I) hydride cluster, [(Ph3P)CuH]6, allows chemoselective conjugate reduction of α,β-unsaturated carbonyl compounds substituted at the γ-position with leaving groups. In addition, the compatibility of the conjugate reduction with organic halides and sulfonate groups is demonstrated.
与有机铜酸盐共轭物添加和共轭物还原的标准方法相反,使用稳定的氢化铜(I)簇[[Ph 3 P)CuH] 6可以使取代在γ上的α,β-不饱和羰基化合物发生化学选择性共轭物还原离开团体的位置。另外,证明了共轭还原与有机卤化物和磺酸盐基团的相容性。
