Compounds of the type Cp*Os(CO)LR (Cp* = η5-C6Me5; L = CO, PMe2Ph; R = Me, Et, i-Pr, CH2Ph), most of them new, have been prepared and their reactions with the electrophiles CF3CO2H, Br2, and HgBr2 have been investigated. All of the electrophiles oxidatively add to give labile, formally osmium(IV) complexes of the type [Cp*Os(CO)(L)(R)(E)]+X-, one of which, [Cp*Os(CO)(PMe2Ph)(Me)(HgBr)]+, has been isolated as the PF6- salt. In all cases, the osmium(IV) complexes decompose in solution to give the normal products of electrophilic cleavage.
