Abstract

Methylene anthrone and its nuclear substitution products are condensed with quinoid compounds containing the grouping p --CH=CH-- in the nucleus, or substitution products thereof in which one halogen atom replaces one hydrogen atom, or compounds convertible under the conditions of the reaction into such substituted quinones. According to examples, methylene anthrone is condensed with a -naphthoquinone, 2-chloro-a -naphthoquinone, a -naphthoquinone-dichloride, benzoquinone, toluquinone, 2 : 5 : 6 - trichlorobenzoquinone, b -naphthoquinone, naphthazarine, and methylene-2-chloroanthrone is condensed with a -naphthoquinone ; 1-chloro-methylene-anthrone is also specified. The products are benzanthrone derivatives having substituents in the bz-1- or bz-2-position, or both, and are in some cases suitable as vat dyes of yellow shades and in others, as dye intermediates.
