Reaction of (CH3NPF3)2 with dry hydrogen fluoride yields CH3NH3+PF6-and the new compound (CH3NHPF4)2.

Fluorodiazadiphosphetidine, 12. Mitt.: Reaktionen von Oktafluoro-1,3,2λ6,4λ6-diazoniadiphosphatetidinen

Reaction of (CH3NHPF4)2 with selected organometallic reagents yields (CH3NPF3)2, while reaction with non-nucleophilic bases such as 1,4-diazabicyclo[2.2.2]octane (DABCO) or 1,8-Bis(dimethylamino)naphthalin and with alkali fluorides yields ionic compounds with the diazoniadiphosphatetidine ring as a dianion.

Fluordiazadiphosphetidine. 8. Mitt. Die photochemische chlorierung von 2,2,2,4,4,4-Hexafluoro-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidin

Chlorination of (CH3NPF3)2 with Chlorine under UV-radiation yields the new compounds CH3(NPF3)2CH2Cl and (ClCH2NPF3)2.

Fluordiazadiphosphetidine, 15. Mitt.: Die Reaktionen von Hexafluordiazadiphosphetidinen mit Fluorwasserstoff

The reaction of fluorodiazadiphosphetidines with dry hydrogenfluoride has been studied thoroughly. Depending on the nature of the substitutents on the nitrogen atom this reaction can take two different courses: a) yielding the octafluoro-1,3,2λ6,4λ6-diazoniadiphosphatetidines1; b) forming the corresponding amine-phosphoruspentafluoride-adducts, which are enabled for various further reactions. A scheme of possible reactions has been established.

Fluordiazadiphosphetidine, 14. Mitt.: Nucleophile Substitutionsreaktionen von 1-Chlormethyl-2,2,2,4,4,4-hexafluor-3-methyl-1,3,2λ5,4λ5-diazadiphosphetidin und 1,3-Bis(chlormethyl)-2,2,2,4,4,4-hexafluor-1,3,2λ5,4λ5-diazadiphosphetidin mit ausgewählten metallorganischen Reagentien

Photochemical chlorination of (CH3NPF3)2 yields ClCH2(NPF3)2CH3(I) and ClCH2(NPF3)2CH2Cl (II). By reaction with organometallics unsymmetric N-substituted hexafluorodiazadiphosphetidines are synthesized. Depending on the nucleophilic strength of the used organometallic the chlorine atom of the N-CH2Cl group can be selectively substituted versus an organic substituent without side-reaction at the phosphorus atom.

Fluordiazadiphosphetidine, 13. Mitt.: Die Reaktion von 2,2,2,4,4,4-Hexafluor-1,3-dimethyl-1,3,2λ5,4λ5-diazadiphosphetidin mit Alkoholen

Nucleophilic substitution reactions of (CH3NPF3)2 with alcohols have been studied. In case of (CH3NPF3)2 as starting material an excess of this compound acts as an HF-acceptor. In this way mono- or di-alkoxysubstituted diazadiphosphetidines are obtained. If the starting material is a substituted ring or if an aromatic alcohol is employed, the alcohol component has to be in form of the lithium salt.
