Abstract
PURPOSE: To obtain the title compound useful as a light stabilizer in high yield, by reacting a phenol with sulfur dichloride in a hydrocarbon to form a sulfide, which is without isolation, oxidized with inexpensive and easily handleable hydrogen peroxide in the same solvent.
CONSTITUTION: A phenol of formula I (R1, R2, and R3 are H, halogen, alkyl cycloalkyl, aryl groups, etc.; R1 is not H, or they may form a ring) is reacted with sulfur dichloride in the presence of a hydrocarbon solvent, e.g. hexane, cyclohexane, or dichloromethane, to give the corresponding 2,2'-bisphenol sulfide, which is, without isolation, oxidized with hydrogen peroxide, preferably a 30W35% aqueous solution, at 30W110°C to form a compound of formula II. The solvent to be used can be recovered by steam distillation after the reaction.
