DEFINITION

Classification: 558/369

(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 alkylated by means of an alkyl halide, alkyl sulfate, substituted alkyl halide or substituted alkyl sulfate.

(1) Note. Examples of processes provided for herein are: [figure] [figure] [figure] [figure]

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