Conjugate additions of alkylchromium reagents mediated by chromium(III) chloride/manganese

Article abstract of DOI:10.1016/S0040-4039(98)80021-X

Benzyl and glycosylchromium reagents generated from the corresponding halides and the couple Cr(III)/Mn were added to activated alkenes to afford Michael adducts. The influence of a ligand around the chromium atom as well as the use of a catalytic amount of chromium chloride were investigated.
