FACILE INSERTION OF ALKYNES INTO IR-P (PHOSPHINE) AND IR-AS (ARSINE) BONDS - 2ND AND 3RD ALKYNE ADDITION TO MONONUCLEAR IRIDIUM COMPLEXES

Alkynes (HC=CH, PhC=CH) insert into Ir-P (phosphine) and Ir-As (arsine) bonds of [Ir(H)(C=CPh)(L(3))(MPh(3))](+) and [Ir-CH=CH-CH=CH)(MeCN)(L(3))](+) in the presence of MPh(3), to produce [Ir(H)(C=CPh)(L(3)) (CH=CHR-M(+)Ph(3))](+) and [Ir(CH=CH-CH=CH)(L(3))(CH=CHR-M(+)Ph(3))](+) [R = H, Ph; L(3) =(CO)(PPh(3))(2);M = P, As].
