In the title compound, C10H12N4, the tetrazole and phenyl rings are planar to within 0.001 (2) and 0.006 (2) Angstrom, respectively. The two rings are not coplanar and have a dihedral angle of 69.07 (9)degrees between them. Each molecule is connected with two adjacent ones by C-H ... N bridges between atoms of tetrazole rings forming chains parallel with the y axis of the unit cell.
Practical synthesis of tetrazoles from amides and phosphorazidates in the presence of aromatic bases
Tetrazoles were effectively synthesized from amides using diphenyl phosphorazidate or bis(p-nitrophenyl) phosphorazidate in the presence of aromaticbases. Various amides underwent the proposed cycloaddition reaction to provide the corresponding tetrazoles. Studies on the racemization of chiral substrates were also performed. Overall, the proposed synthesis method enables the preparation of 1,5-disubstituted
