2-ethoxy-1,3,2lambda5-benzodioxaphosphole 2-oxide

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Pyrocatechol (1.249 g, 11.35 mM) was dissolved in 42 ml of ether and, using 2.297 g (22.70 mM) of triethylamine and 1.849 g (11.35 mM) of ethyl dichlorophosphate, the reaction was carried out at -40° C. to -35° C. and the reaction mixture treated in the same manner as in Reference Example 1. There was obtained 2.159 g (95.0% yield) of ethyl o-phenylene phosphate as a colorless viscous oil. was carried out at -40° C. to -35° C. the reaction mixture treated in the same manner as in Reference Example 1
