A series of 1-alkyl-4-aryl-1,2,3-triazoles (1-methyl-4-phenyl-1,2,3-triazole (1a); 1-propyl-4-phenyl-1,2,3-triazole (1b); 1-benzyl-4-phenyl-1,2,3-triazole (1c); 1-propyl-4-p-tolyl-1,2,3-triazole (1d)) have been prepared through a one-pot procedure involving in situ generation of the alkyl azide from a halide precursor followed by copper catalysed alkyne/azide cycloaddition (CuAAC) with the appr...

Self-immolative linkers offer efficient mechanisms for deprotecting ‘caged’ functional groups in response to specific stimuli. Herein we describe a convenient ‘click’ chemistry method introducing pendant self-immolative polymer backbone through post-polymerization modification. The introduced triazole rings serve both anchor the stimuli-cleavable trigger backbone, while also forming part of sel...

IN THE TITLE COMPOUND (COMMON NAME: iodiconazole), C(19)H(19)F(2)IN(4)O, there is an intra-molecular O-H⋯N hydrogen bond and mol-ecules are linked by weak inter-actions only, namely C-H⋯N, C-H⋯O and C-H⋯F hydrogen bonds, and π-electron ring-π-electron ring inter-actions between the triazole rings with centroid-centroid distances of 3.725 (3) Å.

In the title compound, C9H10N4OS, the dihedral angle between the benzene and 1H-1,2,4-triazole-5(4H)-thione rings is 67.51 (16)°. In the crystal, mol-ecules are liked via N-H⋯O hydrogen bonds, forming chains along the c-axis direction. The chains are linked via O-H⋯S hydrogen bonds, forming corrugated layers lying parallel to the bc plane. The layers are linked via N-H⋯N and N-H⋯S hydrogen bond...

Synthesis of triazole linked macrocycles grafted with glycospiroheterocycle was accomplished by stereo- and regioselective tandem double 1,3-dipolar cycloaddition (1,3-DC) reaction. By this method we could construct complex chiral macrocycles in good yields from the easily available starting materials and we could achieve the synthesis of two heterocyclic rings involving simultaneous formation ...
