Article abstract of DOI:10.1039/DT9900002979

The reaction of 4> with RN2+ (R = 4-CH3C6H4) affords the paramagnetic cationic hydride 4>+, with NO+ the dinitrosyl cation 2>+, and with HBF4*Et2O the cationic dihydride 4>+.Characterization of the complexes by i.r., e.s.r., and variable-temperatrure 1H and 31P-<1H> n.m.r. spectra is described.Variable-temperature 1H n.m.r.T1 measurements at 80, 200, and 400 MHz for both 4> and 4>BPh4 are also reported.The reactivity of the cationic hydrides with CO, RNC, NO,I2, and RN2+ was investigated and the new cations 3>+ (R = 4-CH3C6H4, 4-CH3OC6H4, or 4-ClC6H4) and 4>+ synthesized.The unstable intermediate 4>+ <ν(NO) at 1 680 cm-1> was also detected.
