Bis: and tris:mu-oxo-di:manganese complex salts, useful as catalyst for oxidn. of organic cpds., esp. in oxidative bleach

摘要

Bis- and tris-( mu -oxo)-di-Mn complex salts of formula LMn( mu -O)a( mu -OAc)bMnLxAy (I) are new. Ac = 2-8 C acyl; a = 1, 2 or 3; b = 0 if a = 2 or 3 or b = 2 if a = 1; x = the no. of positive charges and = 2 or 3; A = an anion with 1 or 2 negative charges; y = the equiv. amt. of anion A to balance the positive charges; L = a ligand of formula (II) or (III); R = R' or phenyl; R' = 1-12 C alkyl, 5-10 C cycloalkyl, NH2, NHR2, N(R2)2, OH, OR2 or COOH; R1 = H, R', COOR2, Cl, Br, F or CN; R2 = 1-12 C alkyl or 5-10 C cycloalkyl; g = 2 or 3; m, n 0=4.
