Novel five-coordinate organoiridium(I) complexes of the type Ir(R)(CO)(chel-P3) (chel-P3=PhP(CH2CH2CH2PPh2)2: R = CH2CMe3, CH2SiMe3; chel-P3 = MeP-(CH2CH2CH2PPh2)2: R = CH2SiMe3; chel-P3PhP(CH2CH2PPh2)2; R = CH2SiMe3, 4-MeC6H4) have been prepared from Ir(R)(CO)(PPh3)2 and the respective triphosphine. According to 31P NMR, these compounds are stereochemically rigid at normal temperatures. The reaction
Ir(R)(CO)(chel -P 3)(chel -P 3 = PhP(CH 2 CH 2 CH 2 PPh 2)2类型的新型五配位有机铱(I)配合物:R = CH 2 CMe 3,CH 2森达3 ; CHEL -P 3 = MeP-(CH 2 CH 2 CH 2 PPH 2)2:R = CH 2森达3 ; CHEL -P 3 PHP(CH 2 CH2 PPh 2)2 ; 由Ir(R)(CO)(PPh 3)2和各自的三膦制备R = CH 2 SiMe 3,4 -MeC 6 H 4)。根据31 P NMR,这些化合物在常温下是立体化学刚性的。R(R)(CO)(PPh 3)2(其中R = CH 2 CMe 3或2-MeC 6 H 4)与PhP(CH 2 CH 2 CH 2 PPh 2)2的反应得到四配位衍生物Rh(CH 2 CMe 3)[PhP(CH 2 CH 2 CH 2 PPh 2)2 ]和Rh(2-MeC
