Reaktionsschritte

The autoclave described in EXAMPLE 1 was employed. To this autoclave was charged 11.0 grams (0.040 mole) of anisoin, 2.0 grams (0.0080 mole) of cobalt(II) acetate tetrahydrate, and 70 milliliters of 1-butanol. The autoclave was thereafter charged to 1100 psig with carbon monoxide and heated, with stirring at 800 rpm, to 200° C. Hydrogen was then charged to the autoclave to a total pressure of 3800 psig for a hydrogen to carbon monoxide molar ratio of 2:1. The reaction was allowed to continue for a period of 1 hour, and thereafter cooled to about 70° C. Gas chromatographic analysis of the homogeneous product solution indicated a 90 percent yield of 1,2-bis(4-methoxyphenyl)ethane.
