摘要：

Ultranox626 as a diphosphite ligand showed high selectivity and good yields when used with Rh(CO)(2)(acac) as a catalyst precursor in the hydroformylation of allylbenzene derivatives producing aldehydes, and also in the one-pot hydroformylation-acetalization forming acetals. These reactions proceed smoothly and effectively to produce the linear aldehydes or acetals with high selectivity. The recycling of the rhodium catalyst was carried out after the careful screening and optimization of the reaction conditions in order to maximize the conversion and the selectivity of the reactions.
