Description
Известны способы получени амидов и эфпроамидов кислот трехвалентного фосфора взаимодействием аминов с соответствующими хлораигидридами (1,2).Known methods for the preparation of amides and efproamides of trivalent phosphorus acids are the interaction of amines with the corresponding chloroihydrides (1,2).
Предлагаетс способ получени эфироамидов и амидов фосфористой и фосфинпстой кислот, заключающийс в том, что исходные эфироамиды и амиды фосфористой и фосфинистой кислот переамидируют нагреванием в инертном растворителе или без него с аминами, более зысококип щими, чем те, которые вход т в состав амидной группировки . Выход целевых продуктов около 70%.A method is proposed for the preparation of ether amides and amides of phosphorous and phosphine acids, which consists in the fact that the initial ether amides and amides of phosphorous and phosphorous acids are reamidated by heating in an inert solvent or without it with amines that are higher boiling than those that are part of the amide group. The yield of the target products is about 70%.
Переамидирование амидов и эфироамидов кислот трехвалентного фосфора не описано в литературе. Предложенный способ позвол ет получать амиды и эфироамиды, содержащие в амидной группировке радикалы первичных аминов. Синтезированные вещества могут найти применение в качестве полупродуктов дл получени дохи: ,икатов.Reamidation of amides and esters of trivalent phosphorus is not described in the literature. The proposed method allows to obtain amides and ether amides containing in the amide group the radicals of primary amines. The synthesized substances can be used as intermediates for the preparation of dohi: ikat.
Пример 1. Смесь 4,94 г гексаэтилтриамида фосфористой кислоты и 3,38 г дифениламина нагревают 12 час при 130°, охлаждают и перегон ют. Получают 4,1 г (69,1%) N,N,N N-тeтpaэтил-N,N -дифeнилтриамида фосфористой кислоты, т. кип. 60° при 10 мм; Пд 1,5735.Example 1 A mixture of 4.94 g of phosphorous acid hexaethyl triamide and 3.38 g of diphenylamine is heated for 12 hours at 130 °, cooled and distilled. Obtain 4.1 g (69,1%) of N, N, N N-tetraethyl-N, N-diphenyltriamide phosphorous acid, so Kip. 60 ° with 10 mm; Front 1.5735.
Пример 2. Смесь 5,44 г о-бутилового эфира тетраэтилдиамида фосфористой кислоты нагревают при кипении 3 час, избыток пипиридина отгон ют, остаток перегон ют в вакууме и получают 4,2 с (73%) о-бутилдипиперидилдиамидифосфористой кислоты, т. кип. 138- 140° при 3 мм; 1,4965.Example 2. A mixture of 5.44 g of tetraethyl diamide phosphorous acid o-butyl ester is heated at boiling for 3 hours, the excess pipiridine is distilled off, the residue is distilled in vacuo to give 4.2 s (73%) of o-butyldipiperidyl diamide-phosphorous acid, i.e. 138-140 ° with 3 mm; 1.4965.
№ 144172- -2Предмет изобретени No. 144172- -2 item of the invention
Способ получени амидов и эфироамидов фосфористой и фосфинистой кислот с применением аминов, отличающийс тем, что, исходные амиды и эфироамиды кислот трехвалентного фосфора подвергают переамидированию нагреванием с аминами, более высококип щими , чем те, которые вход т в состав амидной группировки начального амида или эфироамида.A method for producing amides and ethers of phosphorous and phosphinic acids using amines, characterized in that the starting amides and ethers of trivalent phosphorus acids are subjected to heat transamination with amines higher in boiling than those that are part of the amide group of the initial amide or ether amide.
