Ketene gem-dithiols; a convenient one-step procedure from aliphatic active methylenes: reactions and synthesis of polyfunctionally substituted thia- and azaheteroaromatics was written by Zayed, Salem E.. And the article was included in Phosphorus, Sulfur and Silicon and the Related Elements in 1996.Application of 58168-20-0 This article mentions the following:
It has been reported in the current literature that the isolation of certain ketene gem dithiols has failed due to dimerization. Generation of ketene gem-dithiols via trapping with other reactants led to formation of pyridine, pyrrole, pyridothiadiazole and pyrazolone derivatives In the experiment, the researchers used many compounds, for example, Ethyl 5-amino-4-cyano-3-(2-ethoxy-2-oxoethyl)thiophene-2-carboxylate (cas: 58168-20-0Application of 58168-20-0).
Ethyl 5-amino-4-cyano-3-(2-ethoxy-2-oxoethyl)thiophene-2-carboxylate (cas: 58168-20-0) belongs to nitriles. Trimerization of aromatic nitriles requires harsh reaction conditions, high temperatures, long reaction times, and pressure. Nitrile groups in organic compounds can undergo a variety of reactions depending on the reactants or conditions. A nitrile group can be hydrolyzed, reduced, or ejected from a molecule as a cyanide ion.Application of 58168-20-0
