Reaction Steps

Tin methylate Sn(OCH3)2 is produced according to the method disclosed by J. Morrison and H. Haendler, 29 J. Inorg. Nucl. Chem., 393-400 (1967). A catalytic system comprising 66.4 mg of LPtCl2 (L being the same ligand as in example 12) and 15.7 mg tin methylate in a solvent consisting of a mixture of 15 cm3 benzene and 10 cm3 propylene carbonate is introduced under nitrogen into a 100 cm3 stainless steel autoclave reactor equipped with a bar magnet stirring system. Then, 1.23 g styrene is added. The reactor is heated to a temperature of 90° C. and then filled with an equimolar mixture of carbon monoxide and hydrogen (synthesis gas). The resulting mixture is stirred and the reaction continued at 90° C. under a pressure of 100 bars for a time (T) expressed in hours. A mixture of ethylbenzene, 2-phenylpropanol and 3-phenylpropanol is obtained with a degree of conversion (DC). The proportion by weight of ethylbenzene (EB) and the molar ratio (n/b) are determined as above. The results are reported in Table V below.
