Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 3326-71-4, is researched, SMILESS is O=C(C1=CC=CO1)NN, Molecular C5H6N2O2Journal, Russian Journal of Organic Chemistry called Modification of Monocarboxylic Acid Hydrazides with Tropylium Salts, Author is Yunnikova, L. P.; Esenbaeva, V. V., the main research direction is hydrazide tropylium salt modification.Application In Synthesis of 2-Furoic hydrazide.
Nicotinic, isonicotinic, and furan-2-carboxylic acid hydrazides reacted with 2 equiv of tropylium perchlorate or tetrafluoroborate to give the corresponding N’N’-di(cyclohepta-2,4,6-trein-1-yl) derivatives as a result of electrophilic substitution of both hydrogen atoms in the primary amino group. The reaction of furan-2-carbohydrazide with an equimolar amount of tropylium salt gave N’-(cyclohepta-2,4,6-trien-1-yl)furan-2-carbohydrazide.
Compounds in my other articles are similar to this one(2-Furoic hydrazide)Application In Synthesis of 2-Furoic hydrazide, you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
