Reaction of the 3-ethoxymethylene-2,4-alkanediones 1a-c with malononitrile (2) gives the benzonitrile derivatives 3a-c.Compounds 4a-d are obtained by acid or basic hydrolysis of the nitrile group of 3a-c, Sandmeyer reaction leads to the halogenated benzonitriles 5a-f.Compounds 6a,b are available from 3a and O-ethyl- and O-allylhydroxylamine hydrochloride.
