ether with aqueous sodium hydroxide by utilizing the phase transfer ability of tetra n butylammonium hydrogen sulfate the reaction is exothermic and is completed within 1 5 hours at ambient temperature preparation of 2 2 naphthoxy ethyl vinyl ether via reaction with 2 chloroethyl vinyl ether three pounds of 2 naphthol were placed in a three necked round bottom flask equipped with an overhead stirrer and a reflux condenser one liter of dimethyl sulfoxide was used to dissolve the naphthol and to this solution was slowly added 0 8 lb of naoh while keeping the temperature below 50 u00b0 c after the addition of naoh was completed 1 1 liters of 2 chloroethyl vinyl ether were added slowly while keeping the temperature at 60 u00b0 c the reaction mixture was heated at this temperature for 20 hours the progress of the reaction was followed by gc after cooling the reaction product was poured into a polyethylene decantation tank and water was added to separate the product toluene was added to dissolve the product and the toluene phase was washed several times with enough 5 naoh to remove any residual naphthol starting material the toluene layer was dried with anhydrous na 2 so 4 filtered and the toluene was evaporated the product was identified by gc a product yield of approximately 85 based on the weight of the naphthol starting material was obtained with this procedure pd ii acetate 3 36 g 0 01497 moles was dissolved in 375 ml of benzene and filtered through fluted filter paper giving a brown transparent solution to this was added dropwise under.
