High-pressure structural studies and pressure-induced sensitisation of 3,4,5-trinitro-1H-pyrazole
, 2023 Herein we report the first high-pressure study of the energetic material 3,4,5-trinitro-1H-pyrazole (3,4,5-TNP) using neutron powder diffraction and single-crystal X-ray diffraction. A new high-pressure phase, termed Form II, was first identified through

Carbamidine-substituted Pyrazoles [PDF]
Nature, 1951 THE ease with which 1-substituted pyrazoles may be converted into the free imino compounds varies with the nature of the 1-substituent and the reacting substance. Thus, 1,3,5-trimethyl pyrazole may be nitrated1 and 1-phenyl pyrazole reduced to the pyrazoline2 without loss of the N-methyl or N-phenyl groups respectively.

1,5-Dimethyl-4-[(E)-3-phenoxybenzylideneamino]-2-phenyl-1H-pyrazol-3(2H)-one
Acta Crystallographica Section E, 2008 The title Schiff base, C24H21N3O2, adopts an E configuration with respect to the central C=N bond. The pyrazole ring and the central benzene ring attached to the imino group are almost coplanar. The phenyl ring attached to the pyrazole unit is twisted by
