Abstract
Derivatives of p-phenanthrolin, containing the ring system <FORM:0498406/IV/1> where X is sulphur or selenium, are manufactured by treating 4 : 41-dihalogen-p-phenanthrolins with thiourea or selenourea, or with hydrogen sulphide or hydrogen selenide in the presence of an acid-binding agent, or with a salt of hydrogen sulphide or hydrogen selenide. The products possess antalgic action, and may also be used as initial materials in chemical processes. In examples: (1) 2 : 21-dimethyl4 : 41-dichloro-p-phenanthrolin is boiled with thiourea in alcoholic solution to produce 2 : 21-dimethyl-4 : 41-thio-p-phenanthrolin; selenourea similarly yields the corresponding selenium compound; 4 : 41-dichloro-p-phenanthrolin and thiourea similarly yield 4 : 41-thio-p-phenanthrolin; (2) 2 : 21-dimethyl-4 : 41-dichloro-p-phenanthrolin is boiled with thiourea in aqueous suspension; (3) an aqueous solution of sodium or calcium hydrosulphide is gradually added to a boiling alcoholic solution of 2 : 21-dimethyl4 : 41-dichloro-p-phenanthrolin; alternatively, hydrogen sulphide or selenide is passed into the solution, after which sodium hydroxide or calcium hydroxide is added. The starting materials for the examples are obtainable by the action of phosphorus oxychloride on 4 : 41-dihydroxy - p - phenanthrolin or its 2 : 21-dimethyl derivative. Specification 498,405 is referred to.
