1-Dicyanomethylene-3-indanone (1) reacted with carbon disulfide to give the dithiocarboxylic acid derivative (2) which in turn alkylated with methyl iodide and ethyl chloroacetate to give 3 and 4, Indeno[2,1-c]pyridines 5a,b were prepared through the reaction of 1 with phenyl (benzoyl)isothiocyanate. Bromination of 1 with N-bromosuccinimide afforded 2-bromo derivative 8, which reacted with aniline, methyl thioglycolate, and ethyl glycinate to give indeno[2,1-b]pyrrole and indeno[2,1-b]thiopyrane respectively.

1,1-Dicyanomethylene-3-indanone (2) reacted with cinnamonitriles 1a-c to afford fluorenone derivatives 6a-c.Compounds 6a-c were also obtained when treating 2 with 1d-f.The coupling of 2 with aromatic diazonium chlorides resulted in the formation of the hy
