Supported homogeneous film catalysts are described which, in effect, h
eterogenize biphasic systems. Water-soluble catalysts are added to hyd
rophilic films, e.g., polyethylene glycol 600, to catalyze the reactio
ns of hydrophobic substrates. Activities are obtained for the hydrofor
mylation of 1-hexene equal to those obtained in homogeneous systems. E
xperiments are described that indicate that the reactions are occurrin
g in the homogeneous film dispersed over the solid support. (C) 1995 A
