  • Synthesis, Molecular Structure, and Reactivity of Neutral and Cationic Areneosmium(II) Complexes with Diarylcarbenes as Ligands

    (38). The bis(trifluoroacetato) derivatives 14, 15, and 17 react in acetone with water to afford the diaryl(carbonyl)osmium(II) complexes [(η6-mes)OsR2(CO)] (39−41). On the basis of a labeling experiment, a mechanism for this unusual C−C cleavage reaction is proposed. The reaction of the dichloro compounds 28 and 29 with PPh3 in the presence of AgPF6 gives the cationic carbene complexes [(η6-mes)OsCl(PPh3)(CR2)]PF6

  • Sodium oximates as starting materials for the synthesis of half-sandwich-type arene(oximato) and arene(azavinylidene) osmium complexes

    The reaction of [C6H6OsI2((PPr3)-Pr-i)] (1) with Na[ON=CR(2)](R(2)=Ph(2), Me(2), C(CH2)(5)) in the presence of KPF6 leads to the formation of the oximato osmium(II) complexes [C6H6Os(eta(2)-ON=CR(2))((PPr3)-Pr-i)]PF6 (6, 7, 8b) in almost quantitative yield. The mesitylene compounds [(mes)Os(eta(2)-ON=CR'R '')(PR(3))]PF6 (9-14) have been prepared similarly using [(mes)OsCl2(PR(3))] (3-5) as starting materials. The synthesis of [C6H6Os(eta(2)-ON=CMe(t)Bu)((PPr3)-Pr-i)]PF6 (17) has been achieved from [C6H6OsCl2((PPr3)-Pr-i)] (16) which in turn is prepared from [C6H6Os(eta(2)-O2C=O)((PPr3)-Pr-i)] (15) and excess Me(3)SiCl. Reaction of 1, [C6H6OsI2(PMe(t)Bu(2))] (2) and 3 (PR(3) = (PPr3)-Pr-i) with Na[ON=CMe(t)Bu] in the presence of KPF6, in methanol as solvent, unexpectedly yields the azavinylidene complexes [(arene)Os(=N=CMe(t)Bu)(PR(3))]PF6 (18b, 19, 20). The X-ray structural analysis of 18b reveals the presence of a nearly linear Os-N-C fragment with an Os-N distance that is in agreement with typical osmium-nitrogen double bond lengths. Related azavinylideneosmium compounds [(arene)Os(=N=CR'R '')(PR(3))]PF6 (21-26) have been obtained on treatment of the corresponding oximato complexes 7, 10 or 14 with either HN=CR'R '' or, for R'=H and R ''=Ph, the trimethylsilyl derivative.
