“…It was found that photochemical reaction of 1 with isopropyl alcohol gave pinacol and tetraethyl tetrazanetetracarboxylate. Acetaldehyde and 1 gave diacetyl and diethyl hydrazodicarboxylate (2). Recently, Cookson, et al,s reported the photochemical oxidation of ethanol and cyclohexanol in the presence of 1 to give acetaldehyde and cyclohexanone.…”

N‐Vinylformamide (VFA), the simplest member of the enamide group, is the key compound in the synthesis of linear cationic polymers with primary amino groups. In recent decades VFA has been the object of intensive research activity in industry and in universities with the aim of developing an economic method of synthesis. The various principles underlying the synthesis are described and the possibilities for their industrial realisation are discussed. From the large number of methods two variants have now been established as industrial production procedures at BASF and Mitsubishi Kasei Corp. (MKC). VFA is now available in tonne quantities in high purity. An overview of the versatile reaction possibilities of this multifunctional monomer and an extensive list of references are also given. The radical polymerisation to polyvinylformamides and their further reaction to polyvinylamines are not covered in this review.

“…Although some material is eluted at the void volume, fractionation mainly occurs and it is clear that the majority of product is of very low molecular weight. Breitenbach and co-workers [2,3] have shown that in acid solution VP reacts to form pyrrolidone, acetaldehyde, and a dimeric product, 1 ,l-bis(1 '-pyrrolidony1)ethane (D). The following reaction sequence was proposed: Breitenbach's mechanism.…”
