A new diphenylphosphane based on a [beta]-cyclodextrin skeleton that exhibits a dual solubility in ditch-water and in organic solvent was synthesised. Interestingly, a solvent-dependent conformation novelty was evidenced by NMR spectroscopy studies; the self-inclusion of a phenyl categorize of the phosphane moiety into cyclodextrin crater observed in Latin aqua disappeared in organic solvents due to a convert in conformation. Hydrogenation or hydroformylation reactions performed in incredible and in organic solvents showed that this ligand was able to stabilise catalytically animated rhodium species in finding out. In the cover of the hydroformylation reaction, it was demonstrated that regioselectivity was influenced by the solvent-dependent conformation of the ligand <<>>
