Prop-2-enenitrile

The reaction of enamines and imines with acrylamide results in aza-annulation120,121. Other electrophilic alkenes which have been used to alkylate enamines and the products used in hetero- or carbocyclic synthesis include ethyl / -nitroacrylate122, where reaction occurs beta to the nitro not the ester group, 2-(phenylseleno)prop-2-enenitrile [CH2 = C(SePh)CN]123,124, phenyl a-phenylselenovinyl sulphone [CH2 = C(SePh)-S02Ph]124 and phenyl a-bromovinyl sulphone124. An electrophilic allene, phenylsulpho-nylpropadiene, has also been used to alkylate enamines125 (Scheme 44).

Table 2 contains examples of common or semi-systematic names of copolymers. The systematic names of comonomers may also be used thus, the polyacrylonitrile-bfocfe-polybutadiene-fe/oc/r-polystyrene polymer in Table 2 may also be named poly(prop-2-enenitrile)-btocfc-polybuta-l,3-diene-btocfc-poly(ethenylbenzene). lUPAC does not require alphabetized names of comonomers within a polymer name many names are thus possible for some copolymers. 

In addition, they found the MBH adduct, a-methylene-p-hydroxyalk-anenitriles 110 (secondary allylic alcohols), can be conveniently isomerized into 3-aryl-2-(hydroxymethyl)prop-2-enenitriles 111 (primary allylic alcohols) via treatment with aqueous sulfuric acid (20%). These primary alcohols 111 can be... 

Additions of enamines to 2-(phenylseleno)prop-2-enenitrile has facilitated annulation of cyano-containing cyclopentanoid rings, following alkynylation of the ketones resulting from this addition and subsequent radical cyclisation (Scheme 34).
