HCID 357429Phosphonium, diethyldiphenyl-, iodide

実験手順

50 g of diphenylphosphine were mixed with 150 ml of ethanol under nitrogen atmosphere. 37.12 g of potassium carbonate were then added to the mixture and the mixture was stirred. Finally, 125.73 g of ethyl iodide were added dropwise. After 48 hours at 50° C., the ethanol was removed. The product was then dissolved in chloroform. The chloroform was evaporated and the solid washed with diethyl ether and dried under vacuum. 98.45 g of diphenyl-diethyl-phosphonium iodide were obtained (98.5% wt. yield)
