✦ Synopsis

The CIHzNz isomers CH,_N-CN and HN=CH-CN have been selectively generated, the former by flash vacuum pyrolysis of trimethylenetetrazole and SH, lOH-dihydroditetrazolo [ 15-a: 1',5'-d] pyrazine; the latter from azidoacetonitrile and from the lithium and sodium salts of the tosylhydrazone of I-cyanoformamide. CH,=N-CN and HN-CH-CN are unequivocally distinguished by their collisional activation mass spectra. The pyrolysis of dimethylcyanamide gives predominantly CH,=N-CN and CH,-NH-CN.

The enol of glycine, H 2 N-CH C(OH) 2 , is generated in the gas phase by neutralization of the corresponding radical cation, which is available by dissociative electron ionization of isoleucine. Reionization ∼0.6 µs later shows that the isolated enol (2) exists and does not isomerize to the signific

## Abstract The gas phase reaction kinetics of OH with three di‐amine rocket fuels—N~2~H~4~, CH~3~NHNH~2~, and (CH~3~)~2~NNH~2~—was studied in a discharge flow tube apparatus and a pulsed photolysis reactor under pseudo‐first‐order conditions in [OH]. Direct laser‐induced fluorescence monitoring of
