residue remaining on evaporation was chromatographed on 850 g of silica gel (column 4x90 cm) with hexane/acetone (100: 3). The first 300 ml of eluate contained 10.9 g of crude product (30). This was taken up in ether, and washed with 1 % hydrochloric acid and 1 % sodium hydrogen carbonate solution;
As part of our continuing study of the use of N-aryl nitrones in ortho-selective aromatic substitution reactions l-3 , we have investigated the reaction of a number of such nitrones with dichloroketene. These reactions lead to adducts which can be hydrolysed by boiling water or aqueous acid to isati
