Triethyl phosphite → Diethyl 2,4,4-trichloro-1,3-butadien-1-yl phosphate

Participants

Reaction Steps

184 g of 2,2,4,4-tetrachloro-but-3-enal (prepared in accordance with Example 6) were reacted in a manner analogous to that described in Example 6 with 166 g of triethyl phosphite, and 172 g of product were obtained by distillation at 0.2 to 0.3 torr and 121° to 125° C. NMR-spectrum : δ (CH3) : 1.33 ppm, J = 7 Hz; δ (CH2) : 3.95 - 4.47 ppm; δ (C=CH-C) : 6.67 ppm; δ (CH-O-P) : 7.33 ppm, J = 6 Hz.
