A. Berkessel et al., AIR OXIDATION OF A MANGANESE(III) THIOETHER CHELATE AFFORDS THE FIRSTMANGANESE(III) DIHYDROSALEN COMPLEX WITH A PENDANT SULFOXIDE LIGAND, Journal of the Chemical Society, Chemical Communications, (5), 1995, pp. 535-536
The aerobic oxidation of the manganese(iii) dihydrosalen-thioether che
late rac-1 affords the novel manganese(HI) sulfoxide complex rac-2; X-
ray structural analysis of the latter reveals that only one of the two
possible diastereomeric oxidation products is present in the crystal.
