The reaction of phenylpentazole, C 6 H 5 -cyclo-N 5 , with n-butyl lithium in tetrahydrofuran or in diethylether does not yield a lithium pentazolide such as Li(THF) 4  + N 5 −. Instead, a mixture of several primary products is obtained, which probably include lithium 1-n-butyl-5-phenyl-pentaazadienide, Li + [n-C 4 H 9 − N=N−N−N=N−C 6 H 5 ]− and di-n-butyl-phenylhydrazide, Li + [(n-C 4 H 9 ) 2 N−N−C 6 H 5 ]−. After hydrolysis 1,1-di-n- butyl-2-phenylhydrazine, (n- C 4 H 9 ) 2 N−NH−C 6 H 5 , is ob- tained with good yield. This compound is an oil that was characterized by NMR, mass and IR spectroscopy
