Triazole derivatives
R 0280
Synthesis, Characterization, and Structural Investigations of 1-Amino-3-substiSalts, and a New Route to 1-Substituted-1,2,3-triazoles. —
27- 130 tuted-1,2,3-triazolium
Based on an improved route to aminotriazole (II), a new family of quaternary salts,
(IV), is prepared and fully characterized. These salts are convenient starting materials
in the preparation of isomerically pure alkyl triazoles (V), useful pharmaceutical intermediates, thus avoiding the use of expensive 1H-1,2,3-triazole. Several single crystal
X-ray diffraction studies are carried out revealing the expected cationic structures with
complex hydrogen bonding. — (KAPLAN, G.; DRAKE*, G.; TOLLISON, K.; HALL,
