     the aqueous biphasic hydroformylation of 1-octene catalyzed by cobalt complex of the water-soluble ligand trisulfonated tris(biphenyl)phosphine (biphts) was investigated in the absence and presence of various mass transfer promoters (co-solvents, surfactants, cyclodextrins and activated carbon). in the presence of cetyltrimethylammonium bromide, methylated β-cyclodextrin or activated carbon, the co/biphts system allowed the hydroformylation of 1-octene with high conversion (92–95%) and aldehydes selectivity (85–90%). moreover, the catalytic system could be easily reused in the presence of activated carbon as a mass-transfer promoter. in all cases, the conversion and the aldehydes selectivity were found to depend strongly on the ligand/cobalt ratio.
