Abstract
322,745. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 7, 1928. Divided on 322,253. Samples furnished. 2-Methylbenzanthrones are obtained by treating benzanthrones substituted in the 2-position by the group-S.CH2.COR, where R is a hydrocarbon radicle, with or without other substituents in the benzanthrene nucleus, with alkaline saponifying agents. In examples, (1) acetonyl-2-benzanthronyl sulphide (obtained by the action of monochloracetone on the 2-mercaptobenzanthrone made by treating 2-chlorbenzanthrone with sodium sulphide in alcoholic solution) is heated with sodium or potassium hydroxide in the presence of water or ethyl alcohol, or with anhydrous sodium sulphide and ethyl alcohol, and (2) phenacyl-2-benzanthronyl sulphide (from 2- mercaptobenzanthrone and phenacyl bromide) is boiled with alcoholic potash; in each case 2- methylbenzanthrone is obtained. According to the Provisional Specification, 2-alkylbenzanthrones in general may be obtained by treating with alkaline saponifying agents benzanthrones substituted in the 2-position by the group- S.CHR.COR', where Rand R<1> are hydrocarbon radicles, which may be substituted.
