Procedure

To a four-neck 1000 mL reaction flask with mechanical stirrer and thermometer 250 g of triethyl phosphite was added and heated to 150° C.-155° C., then a mixture of 172.7 g (E)-1-Chloro-3,7-dimethyl-2,6-octadiene and 160 g triethyl phosphite was added drop wise. The resulting mixture was stirred at 150° C.-155° C. for an additional 2 h to complete the reaction according to GC. Then cooling the mixture to room temperature, the excessive triethyl phosphite was recycled by vacuum distillation, and 272.8 g of distillate (105-109° C./1 mmHg) was collected as a light yellow transparent liquid with the content of 98.8% according to GC and the yield of 92.1%.
