Description
В спектре, ЯМР промежуточного продукта присутствуют сигналы -219 м.д. (PCh), 4-298 м.д. (РС1 ), а также -75,4 м.д. и 67,2 м.д. Последние сигналы относитс к оргаии.чтри .члорфосфониевому катиону, по-видимому, к Ц11С- и г/ анс-фор.ме.In the spectrum, the NMR of the intermediate product signals are -219 ppm. (PCh), 4-298 ppm (PC1), as well as -75.4 ppm. and 67.2 ppm. The latter signals relate to the org. Thr. Chlorophosphonium cation, apparently to the C 11 C - and g / ans-form.
Пример. К раствору 41,7 г (0,2 мол ) PCL.s в 400 мл хлороформа при комнатной температуре добавл ют 27 г (0,27 мол ) триэтиламина в 50 мл хлороформа. Выдел етс осадок, который к концу добавлени триэтиламина раствор етс . Раствор приобретает темно-красную окраску . Через 1 сут растворитель удал ют при комнатной температуре в вакууме, бурый осадок обрабатывают SOj и летучие продукты удал ют в вакууме. Дихлорангидрид 1-хлор-2-диэтил аминовинилфосфоиовой кислоты экстрагируют эфиром, в остатке остаетс сол нокислый триэтиламин . Эфир отгон ют, а продукт перегон ют в вакууме. Выход 2,1 г (12,7%). Светлокоричневые кристаллы. Т. кип. 125-130°С (0,03 мм рт. ст.). Т. пл. 52°С (из гептана).Example. To a solution of 41.7 g (0.2 mol) of PCL.s in 400 ml of chloroform at room temperature was added 27 g (0.27 mol) of triethylamine in 50 ml of chloroform. A precipitate is precipitated, which dissolves by the end of the addition of triethylamine. The solution becomes a dark red color. After 1 day, the solvent is removed at room temperature under vacuum, the brown precipitate is treated with SOj and the volatile products are removed under vacuum. The 1-chloro-2-diethyl aminovinyl phosphonic acid dichloride is extracted with ether, and the residue remains hydrochloric triethylamine. The ether is distilled off and the product is distilled under vacuum. Yield 2.1 g (12.7%). Light brown crystals. T. Kip. 125-130 ° C (0.03 mm Hg. Art.). T. pl. 52 ° C (from heptane).
