Application
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.
描述：无水氯化镁是白色颗粒或者粉末，易溶于水和乙醇，熔点为714℃，沸点为1412℃，潮解性极强，高于6水氯化镁和2水氯化镁。物理的化学性质基本和6水氯化镁相同。
