Abstract
[Pt(hfac)(2)] (hfac: hexafluoroacetylacetonate) reacts with MeNH2 in CH2Cl2 /MeOH to give an -NHMe adduct complex on one of the carbonyl carbons, (MeNH 3) [Pt(hfac)(hfac-NHMe)] 1 which is a tetrahedral intermediate of a Schiff base complex, [Pt(CF3COCHC(NMe)CF3)(2)] 2. Complex 1 activates H2O, MeOH, M eNO2 or acetone in solution to form the corresponding conjugate base adduct s. The C-C bond in -CH2NO2 adduct 6, easily cleaves and generates nitrometh ane in solution.
