ABSTRACT:
Manganese(IV) complex salts of formula [LMn(μ-O)3MnL]n[XM12O40]m, (I), wherein L is 1,4,7-trimethyl-1,4,7-triazacyclononane, X is P or Si, M is Mo or W, n is 2 or 3, and m is 1 or 2, with the provisos that (i) if X is Si, then n=2 and m=1 and (ii) if X is P, then n=3 and m=2. These compounds are active catalysts in the partial oxidation of various organic compounds with peroxy compounds, e.g., the preparation of ketones from secondary alcohols or the epoxidation of olefins.
