IrIII-Lewis acid for tandem hydroformylation-acetalization of olefins. The best result was obtained over L5-based IrCl3⋅3H2O catalyticsystem which corresponded to 97% conversion of 1-hexene along with 92% selectivity to the target acetals free of any additive. The crystal structure of the novel IrIII-complex of IrIII-L4 indicated that the electron-deficient nature of the involved phosphine warranted Ir-center
The Rh/BINAPa and ZSM-35(10) co-catalyzed tandem hydroformylation–acetalization of olefins is developed to afford the corresponding acetals with high regioselectivities and excellent catalytic activities.
