  Hydrosilylation reaction of allyl acetate (AA) with octakis(dimethylsiloxy)octasilsesquioxane [(HSiMe2O)8(SiO1.5)8] was efficiently catalyzed by chloro(1,5-cyclooctadiene)iridium(I) dimer [Ir(μ-Cl)(COD)]2. The effects of the catalyst amounts and the reaction conditions on the conversion and the product selectivity were investigated. [Ir(μ-Cl)(COD)]2 catalyst was also applied to the hydrosilylation

  Reactions of acyl iodides RCOI (R = Me, Ph) with organosilicon compounds involve cleavage of the Si-O-C and Si-O-Si fragments. Acetyl iodide reacts with alkyl(alkoxy)silanes with evolution of heat, and cleavage of the Si-O bond results in the formation of oligo-or polysiloxanes, alkyl iodides, and alkyl acetates. 1,3-Diacetoxytetramethyldisiloxane is formed in the reaction of acetyl iodide with dimethoxy(dimethyl)silane. Acyl iodides readily react with 1-ethoxysilatrane to give 1-acyloxysilatranes as a result of cleavage of the C-O bond. The reaction of acetyl iodide with hexaethyldisiloxane yields triethylsilyl acetate and triethyliodosilane, while in the reaction with octamethyltrisiloxane iodo(trimethyl)silane and dimethyl(trimethylsiloxy)silyl acetate are obtained.
