In contrast to acyl chlorides, reactions of acetyl iodide with monocarboxylic acids follow the exchange pattern to give the corresponding acyl iodides and acetic acid. The reaction attracts interest from the preparative viewpoint as a simple and convenient route to acyl iodides. Acetyl iodide reacts with phthalic acid, yielding acetic acid and phthalic anhydride, while the reaction of acetyl iodide with oxalic acid leads to formation of acetic acid, carbon(II) oxide, and molecular iodine.

Reaction of [AsPh(4)][Rh(CO)(2)I-2] (1) with RCOI yields complexes [AsPhh(4)](2) [RCORh(CO)I-3](2) (2, R = Me; 3, R = Et; 4, R = n-Pr; 5, R= i-Pr). The (CO)-C-13 scram bling process for complexes [AsPh(4)][RCORh((CO)-C-13)(S)I-3] (R = Me, Et; S = CD3CN) along with the skeleton isomerization of [AsPh(4)][RCORh(CO)(S)I-3] (R = n-Pr, i-Pr) was determined by H-1 NMR spectroscopy. Rates of CO insertion into the Rh-C bond in [AsPh(4)][R-Rh(CO)(3)I-3] (R = Me, n-Pr, i-Pr) were determined. Thermolysis of [AsPh(4)] [MeCORh(CO)(CD3CN)I-3] (6) in CD3CN gives methyl iodide in contrast to [AsPh(4)] [i-PrCoRh(Co-13) (CD3CN)I-3] (7) and [AsPh(4)][n-PrCORh((CO)-C-13)(CD3CN)I-3] (8) which give only propene as the organic fragment.
