The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function. [PDF]

Angew Chem Int Ed Engl
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.

A magnetically recoverable copper nanocatalyst for tandem tetrazole synthesis and regioselective N-functionalization [PDF]

RSC Advances
A magnetically recoverable copper nanocatalyst supported on silica-coated maghemite (CuNPs/MagSilica) was developed and applied in the tandem synthesis and regioselective N-functionalization of tetrazoles.

The Stabilization of High-Nitrogen Systems: 10 Catenated Nitrogen Chain. [PDF]

Chemistry
Improving the understanding of high‐nitrogen materials. ABSTRACT High‐nitrogen materials have attracted intense interest in recent decades due to their unique chemical, physical, and biological properties. Stabilizing high‐nitrogen materials is often challenging as they become more unstable with increasing nitrogen catenation and nitrogen mass ...

Ambident reactivity of enolizable 5-mercapto-1H-tetrazoles in trapping reactions with in situ-generated thiocarbonyl S-methanides derived from sterically crowded cycloaliphatic thioketones [PDF]

Beilstein Journal of Organic Chemistry
The in situ-generated thiocarbonyl S-methanides (thiocarbonyl ylides), derived from cycloaliphatic thioketones, are efficiently trapped by enolizable 1-substitued 5-mercapto-1H-tetrazoles and formation of the corresponding N–H or S–H insertion products ...

Tetrazoles: a new class of compound for crystallization modification [PDF]

, 2010
Tetrazoles are a class of organic compound often used as carboxylic acid analogues. This analogous behaviour is shown to extend to crystallization modification, that is, tetrazoles are also able to influence crystal growth and morphology although in a ...
