0 where R and R 'are aliphatic. It was first necessary to develop a satisfactory method for the preparation of nitroolefins. for the preparation of nitroolefins. We found that it improved the yield to add methanol to the aqueous sodium bicarbonate solution. The procedure is generally reliable and yields of nitro-olefin are usually 90-9595 with the best yields from esters of nitroalcohols with nine or more carbon atoms. The yield from nitroalcohol to ...
