Remarkably easy one-electron reduction of 16-electron molybdenum nitrosyls: mechanistic implications for the formation of alkoxy, amido, hydrazido, and thiolato complexes containing the tris-3,5-dimethylpyrazolylborato-ligand

Abstract

Reduction of [Mo{HB(3,5-Me₂C₃HN₂)₃}(NO)I₂], A, is achieved electrochemically intetrahydrofuran (Pt or C electrodes), and in basic solvents chemically, giving paramagnetic A^– from which I^– dissociates affording paramagnetic [Mo{HB(Me₂C₃NH₂)₃}(NO)I]; these reduction products are important intermediates in the formation of [Mo{HB(Me₂C₃HN₂)₃}(NO)IQ], where Q = OR, NHR, NHNR¹R², and SR, from A and ROH, RNH₂ R¹R²NNH₂, and RSH.
