1,2,4-Diazaphospholium Ionic Pairs Compounds

The article is based on 1-H-1,2,4-diazaphospholide to synthesize three 1,2,4-diazaphospholium ionic pair compounds with NBS?CF3SO3H and(CH3)3O(BF4).All three of complexes have been fully characterized:1.The reaction of 3,5-disubstituted-1,2,4-diazaphospholide and Trifluoromethanesulfonic acid in a molar ratio of 2:3 gave complexes [(3,5-t Bu2dp)4(CF3SO3)2]2+ [(CF3SO3HCF3SO3)-]2(1).2.The reaction of 1,3,5-triphenyl-2,4-diazaphosphole with trimethyloxonium tetrafluoroborate afforded complex[(2-CH3-1,3,5-Ph3dp)+(BF4)-](2).3.The reaction of 3,5-disubstituted-1,2,4-diazaphospholide with N-bromosuccinimide produced [3,5-t Bu2dp-NBS](3).4.Far infrared and Moose Bauer Spectrum Characterization of Sn3[3,5-t Bu2dp]4O(4).
