rhodium‐catalyzed hydroformylation reaction of 1‐decene. We showed that, using ionic β‐CDs, the catalytic activity could be improved without a detrimental impact upon the regioselectivity. A linear/branched aldehyde ratio as high as 8.6 could be achieved. The best results were obtained with stoichiometric quantities of ionic randomly methylated β‐CDs with respect to the phosphane with a beneficial effect on the
were evidenced according to the degree of sulfonation. The monosulfonated phosphanes formed well organized micelle‐like aggregates while the disulfonated phosphanes formed heterogeneous and disorganized vesicle‐like assemblies. The efficiency of these amphiphilicphosphanes was evaluated in the aqueous biphasic, palladium‐catalyzed cleavage of allyl alkyl carbonates.
