Disclosed is a one step hydroformylation process for preparing a 1,3-diol, comprising the reaction of an oxirane with syngas at hydroformylation conditions in an inert solvent in the presence of a hydroformylation catalyst comprising a ruthenium (+1)-phosphine bidentate: cobalt (-1) complex, wherein the ligated metal is ruthenium, under conditions which preferably upon completion of the oxirane/syngas reaction cause a phase separation of the reaction mixture into a solvent phase which is rich in catalyst and a second phase which is rich in the 1,3-diol, recycling the phase rich in catalyst directly to the hydroformylation reaction for further reaction with previously unreacted starting materials, thus permitting valuable hydroformylation catalyst to be recycled without degradation or exposure to downstream processing and recovering the 1,3-diol from the second phase rich in 1,3-diol. |
