Participants

Reaction Steps

Pyrocatechol (0.993 g, 9.02 mM) was dissolved in 50 ml of ether and, using 1.825 g (18.04 mM) of triethylamine and 1.723 (9.02 mM) of n-butyl dichlorophosphate, the reaction was carried out at -5° C. to 0° C. and the reaction mixture treated in the same manner as in Reference Example 1. There was obtained 1.914 g (93.0% yield) of n-butyl o-phenylene phosphate as a colorless viscous oil. 1H-NMR(CDCl3) δ: 0.7~2.0(5H, m, C--CH2CH2CH3), 4.13 and 4.28(2H, each t, J=6.5 Hz, P--O--CH2), 7.10 (4H, s, ##STR64## Signals for trace amounts of ether and triethylamine were also observed.
