Reaction Steps

A total of 13 mmol of nitrogen monoxide was introduced into a mixture of 1 mmol of 1-hydroxyphthalan, 0.1 mmol of N-hydroxyphthalimide, and 5 ml of acetonitrile, and the resultant mixture was stirred at 60° C. for 2 hours. Isolation of products in the reaction mixture by column chromatography on a silica gel revealed that 1-hydroxyphthalane was converted, at a rate of 99%, into phthalaldehyde (yield: 95%).
