2,2-Difluoro-4,6-bis(trifluoromethyl)-1,3,5,2λ5-triazaphosphinine (1) reacts with CMe3NH2 and MeOH with cleavage of HF to give the substituted compounds 3 and 4.By addition of released HF, the hybrid-ionic compound 5 is formed.A stable 2-fluoro-2-hydroxytriazaphosphinine, N(CCF3N)2PF(OH) (6), is synthesized by the reaction of 1 with CMe3OH, CMe3SiMe2OH, or (CMe3)2Si(OH)2, alkyl fluorides or silyl fluorides being cleaved of. 2,2-Dichlorotriazaphosphinine 2 reacts with (CMe3NH)2SiMe2 to give N(CCF3N)2P(Cl)NHCMe3 (7). N(CCF3N)2P(F)NRSiMe3, R = C6H5 (8), SiMe3 (9), is formed by the reaction of 1 with (Me3Si)2NR.Interaction between 1 and heptamethylsilazane in the molar ratio 1:2 yields the disubstituted product 10 with and exocyclic P=N double bond.The reaction of alkoxides, silanolates, and thiolates with 1 gives mono- (11 - 17) and disubstituted (18 - 23) compounds.A migration of methyl and ethyl groups, with formation of an exocyclic P=O bond, is observed (11, 12).
