Abstract

Decomposition of trans -ROIr(CO)(PPh₃)₂ in the presence of PPh₃ leads to HIr(COXPPh₃)₃for R = Me, n-Pr, and i-Pr. For R = H, t-Bu, or Ph, this decomposition is not observed. For R = /-Pr similar quantities of acetone and 2-propanol are observed with total yield of 90% based on starting iridium complex. Propanal is formed for R = n-Pr. The reaction between trans-i-PrOIr(CO)(PPh₃)₂and HIr(CO)(PPh₃)₃readily yields 2-propanol. Thus a /3-hydrogen abstraction to yield organic carbonyl and HIr(CO)(PPh₃)₃ is indicated with 2-propanol possibly formed by a binuclear reaction between trans - i-PrOIr(CO)(PPh₃)₂ and HIr(CO)(PPh₃)₃.
