MANGANESE(II) CHLORIDE HYDRATE Chemical Properties,Usage,Production

Uses

Starting material for preparation of organomanganese chloride reagents; in combination with RLi or RMgX catalyzes reduction of vinyl and aryl halides, stereoselective coupling of vinyl iodides, and alkylation of enol triflates; also used for Mn-Cu-catalyzed conjugate addition of RMgX to enones and for Mn-catalyzed acylation of RMgX by acyl chlorides; in combination with NaBH4 is diastereoselective reducing agent; starting material for the preparation of Mn enolates regio- andstereo-selectively.
