Participants

Reaction Steps

55.0 Parts of resorcinol, 17.8 parts of dimethyl prenylphosphonate and 5.0 parts of Fulmont 237® were stirred at 125° C. for 18 hours. The cooled reaction mixture was then diluted with ether, filtered free of catalyst, and poured into 500 parts of water. The oil which separated out was then washed by decantation with water and extracted with ether. Following further washes with sodium bicarbonate solution and water, the ether solution after concentration yielded dimethyl 3-(2',4'-dihydroxyphenyl)-3-methyl-butane-phosphonate, m.p. 142°-3° C., with the following percentage composition by weight.
