چکیده

In the title compound, C28H23N3O, the 1,2,4-triazole ring deviates slightly from planarity adopting a (N3)TC2 conformation which is distorted towards an EC2 conformation. The plane around the ethyl-ene unit makes a dihedral angle of 17.32 (11)° with the mean plane [r.m.s. deviation = 0.036 (1) Å] of the 1,2,4-triazole fragment. The dihedral angles between the four phenyl rings and the 1,2,4-triazole ring are 31.01 (10), 49.01 (8), 78.55 (6) and 41.51 (9)°. In the crystal, mol-ecules are linked along [100] by weak C-H⋯O hydrogen bonds.

Synthesis of 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones and their isatin-3-imine derivatives.

Iminoester hydrochlorides 1 have been synthesized. These compounds were then converted into ester ethoxycarbonyl hydrazones 2, from which in turn a new series of substituted 4-amino-4,5-dihydro-1H-1,2,4-triazole-5-ones, 3, was then prepared. Finally a set of isatin imine derivatives 4 was obtained from the reaction of compounds 3 with isatin. The structures of all the new synthesized compounds ...
