The first chiral racemic Fischer-type aminocarbene complex bearing a C2 symmetry amine: stereochemical characteristics and application to Michael addition reactions

The synthesis of [trans-methyl(2,6-dimethylmorpholino)carbene]pentacarbonylchromium(0) complex (3) (shown as structure I) is reported, together with the stereoselective Michael addn. of the conjugate base of complex 3 to enones.
