tributyl(3-hydroxypropyl)phosphanium;chloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into a 1 L-four-necked flask equipped with a stirrer, a thermometer and a distillation line, was added the obtained tri-n-butyl(3-hydroxypropyl)phosphonium chloride dissolved in 500 ml of acetonitrile. The solution was heated under a normal pressure while stirring and about 200 ml of acetonitrile was distilled. A condenser having a calcium chloride tube was installed, 1.5 g of hydroquinone monomethyl ether was added as a polymerization inhibitor, and 75.8 g (0.725 mol) of methacryloyl chloride was added thereto dropwise at 50° C. over 2 hours through a dropping funnel, then the solution was maturated for 3 hours at the same temperature as above. The absence of an unreacted substance was confirmed using FT-IR, and the reaction solution was concentrated and dried with a vacuum pump to give 290.3 g of a slightly yellow liquid. The titration purity was 94.6% and the yield was 100.0%.
