DEFINITION

Classification: 558/367

(under subclass 357) Processes wherein an acyclic or alicyclic carbon, which is adjacent to a benzene ring or to an atom double or triple bonded to a noncarbon atom, is cyanalkylated by means of reaction with acrylonitrile or hydrocarbyl-substituted acrylonitrile.

(2) Note. The acyclic or aliycylic carbon of this subclass is generally considered to by the carbon of a reactive methylene group.
