Yield:70127-50-3 73%

Reaction Conditions:

in tetrahydrofuran;

Steps:

R.1 Synthesis of o-(diphenylphosphinylmethyl)phenol

REFERENCE EXAMPLE 1 Synthesis of o-(diphenylphosphinylmethyl)phenol In a reactor equipped with a thermometer, a stirrer and a condenser were placed 99.2 g of o-(hydroxymethyl)phenol and 400 ml of tetrahydrofuran. They were made into a uniform solution. Thereto was added 184 g of ethyldiphenylphosphinite. The resulting mixture was subjected to reaction for 3 hr with heating and stirring. The reaction mixture was cooled and the resulting white crystal precipitate was separated by filtration and then dried to obtain 180 g of o-(diphenylphosphinylmethyl)phenol. Yield: 73% Melting point: 179° C.
