Perfluoroalkyl-substituted triazapentadienes and their metal complexes.
Triazapentadienides, C(3)F(7)-C(=NR)-N=C(NHR)-C(3)F(7), result from the reaction of primary amines RNH(2) with the fluorinated imine C(3)F(7)-CF=N-C(4)F(9). The aniline derivative (R = Ph) is a weakExpand

Structure and Dynamics in a Bis(perfluoroalkyl)triazapentadiene Methylmercury Compound
The compound [Ph2N3C2(C3F7)2]HgCH3 was synthesized from Na[Ph2N3C2(C3F7)2] and CH3HgCl. In solution, it exists as a mixture of two isomers that interconvert slowly on the NMR time scale. Both isomersExpand

Reactions of the perfluoroalkyltriazapentadiene Ph2N3C2(C3F7)2H with acids, bases, and water.
Treatment of the bis(perfluoroalkyl)triazapentadiene PhN=C(C(3)F(7))-N=C(C(3)F(7))-NHPh, 2, with bases affords salts of the conjugate base. Alkylation of the Na(+) salt with CH(3)I yieldsExpand
