Procedure

In a manner similar to Example 17, 126.5 g of benzyl chloride, 794 g of a 9 wt-% solution of sodium ethylate in ethanol, 12 g CoCl2. 6 H2O, 6 g manganese powder and 1 g Na2S2O4 were reacted with CO. After the usual processing, 8 g of benzyl chloride, 109 g of phenylacetic acid ethyl ester (yield 71%), 8 g of phenylacetic acid (yield 6%) and 1 g of ethylbenzyl ether were isolated.
