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

  摘要：

  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.
