Hydroformylation of formaldehyde to give glycolaldehyde with halide-promoted Rh4(CO)12
Abstract
Hydroformylation of paraformaldehyde and 37% aqueous formaldehyde to give glycolaldehyde with selectivity up to ca. 90% has been carried out in acetone at 90–140 °C and 100–140 atm of carbon monoxide–hydrogen with halide-promoted Rh4(CO)12 as catalyst precursor.
