In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis of furanic derivatives with CH-acid properties. Behavior of 1-(2-furyl)alkylidene derivatives of malonic acid in presence of bases, published in 1978, which mentions a compound: 3194-15-8, mainly applied to furylethylidenemalonitrile cyclodimerization; malononitrile furylethylidene cyclodimerization; tautomerism iminocyclohexenecarbonitrile derivative; cyclohexenecarbonitrile imino preparation tautomerism, Quality Control of 1-(Furan-2-yl)propan-1-one.
Reaction of MeCR:C(CN)2 (R = 2-furyl) with an equimol amount MeONa in MeOH for 8 h at 20° gave 63% the cyclodimer I. Spectral data showed that I exists as a tautomeric mixture EtCR:C(CN)2 did not undergo similar dimerization reaction.
Here is a brief introduction to this compound(3194-15-8)Quality Control of 1-(Furan-2-yl)propan-1-one, if you want to know about other compounds related to this compound(3194-15-8), you can read my other articles.
