The compounds [C6H6Os(PR3)I2] react with AgPF6 and 1-alkynes R′CCH to give, depending on the substituent R′, either neutral alkinyl or cationic vinylidene complexes [C6H6Os(CCR′)(PR3)I] (R′ = Ph, Tol) and [C6H6Os(=C=CHR′)(PR3)I]+ (R′ = H, Me, nBu, tBu), respectively. The reaction of [C6H6Os(PMetBu2)I2] with AgPF6 and HCCCO2Me gives the five-membered ring compound [C6H6(CH=C(I)C(OMe)O)(PMetBu2)]PF6
化合物[C 6 H 6 Os(PR 3)I 2 ]与AgPF 6和1-
炔烃R'CCH反应,根据取代基R'得到中性炔基或阳离子亚
乙烯基络合物[C 6 H 6 Os(CCR')(PR 3)I](R'= Ph,Tol)和[C 6 H 6 Os(= C = CHR')(PR 3)I] +(R'= H,Me,n Bu,t Bu)。[C 6 H 6 Os(PMe t Bu 2)I 2 ]与AgPF 6和HCCCO的反应2 Me给出五元环化合物[C 6 H 6(CH = C(I)C(OMe)O)(PMe t Bu 2)] PF 6,经NaI处理并随后消除CH 3 I,形成中性络合物[C 6 H 6(CH = C(I)C(O)O)(PMe t Bu 2)]。阳离子[C 6 H 6 Os(= C = CHR')(PR 3)I] +(R'= Me,n Bu,t Bu)与碱(MeNH 2,Me 2 NH,1
