Cyanamide‐defect and heptazine/triazine (H/T) junction in g‐C3N4 (CN) have commonly been considered as an effective strategy for solar‐driven artificial H2O2 photosynthesis. However, their synergistic effect is still ambiguous regarding how to manipulate

A practical two-step synthesis of N,N'-disubstituted cyanamides consists in the low-temperature metalation of N-substituted 5H-tetrazoles that undergo spontaneous cycloreversion at 0 °C releasing dinitrogen, and forming N-metalated cyanamides that can be

Copper-Catalyzed Alkenylation of Cyanamides
Organic Letters, 2017An efficient procedure for the copper-catalyzed cross-coupling between a broad range of cyanamides and iodoalkenes is reported. Upon reaction with catalytic amounts of copper(I) iodide and 2,2'-bisimidazole in the presence of cesium carbonate in DMF at 80 °C, a fast, regioselective, and stereoretentive cross-coupling occurs.

The cyanamide–isocyanamide rearrangement
The Journal of Chemical Physics, 1980A b initio self-consistent field (SCF) and correlated SCEP calculations have been used to study the relative energies and structures of cyanamide, isocyanamide, and the transition state for the rearrangement reaction. Isocyanamide is found to be 53 kcal less stable than cyanamide, larger than the typical isocyanide–cyanide energy difference ...

WHEN wool fibres are exposed to the action of light and air, the cystine linkages undergo decomposition with loss of sulphur and development of sulphydryl and aldehyde groups. In consequence, the increased alkali-combining power of the exposed tips, as compared with the unexposed roots of wool staples above pH 8, has been referred to the presence of ...

Embryogenic tissue cultures of soybean were transformed by particle bombardment with a vector pCHZ-II that carries the coding sequence for cyanamide hydratase (Cah), an enzyme that converts toxic cyanamide to urea, from the soil fungus Myrothecium verrucaria.

Eczematous erythroderma induced by cyanamide
Contact Dermatitis, 1999The term cyanamide is applied to both free cyanamide (carbimide) and its calcium salt (calcium carbimide). It is extensively used as a fertilizer, herbicide and chemical intermediate (1). In the medical field, cyanamide was introduced into Canada, Europe and Japan in 1956 as a treatment for chronic alcoholism.
