Popis: The reactivity of some monosubstituted fluorodiazadiphosphetidines towards potassium fluoride utilizing 18-crown-6-ether as a phase transfer catalyst has been studied. The following compounds were investigated: 2,2,2,4,4-pentafluoro-4-methoxy-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine, 2,2,2,4,4-pentafluoro-4-methylamino-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine, 2,2,2,4,4-pentafluoro-4-methylthio-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine, and a 1:1 mixture of 2,2,2,4,4-pentafluoro-4-(N2,N2-dimentyl-hydrazino)-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine and 2,2,2,4,4-pentafluoro-4-methylamino-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine. All reactions proceeded in a similar way and led to the disubstituted derivates of the starting materials and the potassium salt K2(CH3NPF4)2. In this way 2,2,4,4-tetrafluoro-2-methylamino-4-(N2,N2-dimethylhydrazino)-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidine has been synthesized for the first time and a new way has been found for the synthesis of several compounds reported in literature.
