Participants

Reaction Steps

A mixture of 24.9 g (0.10 moles) dibutyltin oxide, 30.4 g (0.20 mole) 4-hydroxyphenylacetic acid, and 300 ml toluene were charged to a 3-necked round bottom flask equipped with a stirrer, thermocouple or thermometer, and condenser with a DEAN-STARK water trap, and heated at reflux temperature until all the water of reaction was collected in the trap. The toluene was removed using a flash evaporator to yield 53 g (99%) of dibutyltin bis(4-hydroxyphenyl acetate) having a melting point of 121°-126° C.
