SOLID-STATE REACTIONS OF IRIDIUM(I)-1,5-CYCLOOCTADIENE COMPOUNDS WITH CO - SYNTHESIS OF CATIONIC (1,5-CYCLOOCTADIENE)CARBONYLIRIDIUM(I) COMPLEXES

[Ir(COD)(CO)2(L)]ClO4 (1) and [Ir(COD)(CO)(L)2] ClO4 (2) (COD = 1,5-cyclooctadiene; L = PPh3 (a), AsPh3 (b)) have been prepared from the solid-state reactions of [Ir(COD)(L)(PhCN)]ClO4 (3) and [Ir(COD)(L)2]ClO4 (4), respectively, with CO (1 atm) at 25-degrees-C. The products 1 and 2 have been characterized by conventional analytical and spectroscopic methods as well as single-crystal X-ray crystallographic analysis for [Ir(COD)(CO)2(PPh3)]ClO4 (1a) and [Ir(COD) (CO)2(ASPh3)] ClO4 (1b).
