Application

Starting material for preparation of organomanganese chloride reagents; catalyst for 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- and stereo-selectively.
A novel high-spin hexanuclear Mn(III) cluster, [NaMn6(OMe)12(dbm)6]+, was synthesized via MnCl2 oxidation with simultaneous NaOMe promoted aggregation. This cluster has an unprecedented cyclic structure and 24 unpaired electrons in its ground state. Also used in the formation of an active Mn(0) speciesuseful for radical cyclization reactions.

Chronic exposure to Mn results in the development of a neurological disorder known as manganism characterized by neurological deficits resembling that seen in Parkinsonism. Although dopaminergic neurons within the nigrostriatal pathway appear intact, Mn-induced irregularities in DA transmission have been
