где R - арил или бензил, которые могут найти применение в качестве катализаторов в реакци х карбопиимидообразовани , а также в качестве полуп1Х )дуктов дл получени аминометиль- ных производных фосфора, обладающих полезными свойствами.where R is aryl or benzyl, which can be used as catalysts in carbopiimide formation reactions, and also as semi-1X compounds for the preparation of aminomethyl phosphorus derivatives having useful properties.
Известен способ получени замещенных фосфетанов восстановлением соответствующих окисей фосфетанов трихлорсиланом в присутствии триэтиламина в бензоле при нагревании в атмосфере азота, с последующей обработкой реакционной смеси 20%- ным раствором гидроокиси натри fl.A known method of producing substituted phosphetanes by reduction of the corresponding oxides of phosphetanes with trichlorosilane in the presence of triethylamine in benzene with heating in a nitrogen atmosphere, followed by treatment of the reaction mixture with a 20% sodium hydroxide solution fl.
Наиболее близким к изобретению по технической сущности и достигаемому ре-The closest to the invention to the technical essence and the achieved re-
зупьтату вл етс способ получени 1,3азафосфетидинов , заключающийс в том, что дифе идборилоксиметилоксиметилфенил- фосфин нагревают до 165-180°С в атмосфере инертного газа, с последу ощей обработкой полученного 2,5-дифенил-2-бор- -1,3,5-диоксафосфоринана первичным амином в среде органического растворител при комнатной температуре 2.The result is a method for producing 1,3azaphosphetidine, which consists in that the diphoboridyloxymethyloxymethylphenylphosphine is heated to 165-180 ° C in an inert gas atmosphere, followed by treatment of the resulting 2,5-diphenyl-2-boron-1.3, 5-dioxaphosphorinan primary amine in an organic solvent at room temperature 2.
К недостаткам известного способа относ тс двухстадййность процесса, необходимость проведени первой стадии процесса при высокой температуре и в атмосфере инертного газа, а также не всегда высокие выхода целевых продуктов (43-85%).The disadvantages of this method include the two-stage process, the need to carry out the first stage of the process at high temperatures and in an inert gas atmosphere, and also not always high yields of the target products (43-85%).
Целью изобретени вл етс упрощение процесса и повышение выхода целевых продуктов.The aim of the invention is to simplify the process and increase the yield of the target products.
Поставленна цель достигаетс предлагаемым способом получени 1,3-азафос- фетидинов указанной общей формулы, который заключаетс в том, что дифенилборилоксиметилоксиметилфенилфосфин подвергаThe goal is achieved by the proposed method of producing 1,3-azafosfetidinov indicated General formula, which consists in the fact that diphenylboroxymethyloxymethylphenylphosphine subjected to
