| Popis: | Reaction of equimolar quantities of [WI2(CO)(NCMe)(η2-MeC2Me)2] and Ph(H)CNNHCONH2 or R(R1)CNNHCSNH2 (R = R1 = Me, Et; R = H, R1 = Ph; R = Me, R1 = Et, Prn, But, Ph) in CH2Cl2 at room temperature gave the cationic bis(but-2-yne) complexes [WI(CO){Ph(H)CNNHCONH2}(η2-MeC2Me)2]I or [WI(CO){R(R1) CNNHCSNH2}(η2-MeC2Me)2]I in good yield. The cationic nature of these complexes was confirmed by reaction of [WI(CO){Me(Ph)CNNHCSNH2}(η2-MeC2Me)2]I with Na[BPh4] in acetonitrile to afford the tetraphenylborate exchanged product [WI(CO) {Me(Ph)CNNHCSNH2}(η2-MeC2Me)2][BPh4]. Refluxing a CHCl3 solution of [WI(CO) {Et2CNNHCSNH2}(η2-MeC2Me)2]I for 14 h gave the mono(but-2-yne) complex [WI2(CO) {Et2CNNHCSNH2}(η2-MeC2Me)]. |
