  摘要：

  Alkyl-carbonyl-iridium [Ir(CH3)(CO)(eta(2) - O2CR ')(PPh3)(2)](+) (1, R ' = CH3, Ph, p-C6H4CH3) react with alkynes (RC &3bond; CH; R = Ph, p-C6H4CH3) in the presence of NEt3 to give acyl-alkynyl-iridium Ir(C(=O)CH3)(-C &3bond; CR)(eta(2) -O2CR ')(PPh3)(2) (4) which further react with RC &3bond; CH to give alkyl-carbonyl-cis-bis(alkynyl) iridium Ir(CH3)(CO)(C &3bond; CR)(2)(PPh3)(2) (5). cis-Bis(alkenyl)iridium complexes, Ir(-CH=CH2)(2)(eta(2) -O2CCH3)(PPh3)(2) (6) and Ir(-CH=CHCH=CH)(eta(2)-O2CCH3)PPh3)(2) (7) react with substituted alkynes RC &3bond; CH (R = Ph, p-C6H4CH3, cyclohex-1-enyl) to give cis-bis(alkynyl) Ir(C &3bond; CR)(2)(eta(2)-O2CCH2)(PPh3)(2) (9) that further react with RC &3bond; CH to undergo the alkyne insertion reaction into the Ir-O bond to produce iridacycles containing vinyl acetate ligands, Ir(C(=CHR)OC(CH3)=O)(-C &3bond; CR)(2)(PPh3)(2) (8).
