Guanidine reactivity
WebBecause the guanidino group contains two reactive nitrogens, rather than only one as in the lysine side chain, it shows a more diverse chemistry. Reaction with dicarbonyl compounds readily yields five membered, imidazole-type, rings systems, with various substitutions and regio-isomers. WebGuanidine Salts e.g., Guanidine hydrochloride, guanidinium chloride, guanidine thiocyanate: Forms toxic gases (e.g., chloramine, chlorine, and hydrogen cyanide) and can form …

Webguanidine, an organic compound of formula HN=C(NH2)2. It was first prepared by Adolph Strecker in 1861 from guanine, which had been obtained from guano, and this is the origin of the name. The compound … WebGuanidines are a group of organic compounds sharing a common functional group with the general structure (R 1R 2N) (R 3R 4N)C=N−R 5. The central bond within this group is that of an imine, and the group is related structurally to amidines and ureas. Examples of guanidines are arginine, triazabicyclodecene, saxitoxin, and creatine .

WebThis feature article discusses the various mechanistic aspects of guanidine -catalyzed reactions. Guanidines are well known as strong organic bases; however, in the first section, three most common commercially available guanidines, TMG, TBD and MTBD, will be used to illustrate the use of guanidines as nucleophilic catalysts.
WebBleach is very reactive and if it mixes with incompatible chemicals, it can produce high hazard by-products and toxic gases. What are the hazards of Bleach? Bleach is an oxidizer and corrosive. Exposures may cause irritation or damage to the skin, eyes, and the respiratory tract.
