Abstract

The invention comprises phosphates of general formula <FORM:0893172/IV (b)/1> <FORM:0893172/IV (b)/2> <FORM:0893172/IV (b)/3> wherein R stands for <FORM:0893172/IV (b)/4> <FORM:0893172/IV (b)/5> n is 1-9, and the alkyl group contains more than one carbon atom; and certain salts thereof with bases; and the manufacture thereof by treating the corresponding quinones with dibenzyl phosphite or an alkyl benzyl phosphite in the presence of a base, and optionally thereafter debenzylation and/or acylation. Quinone starting materials may be prepared by treating an appropriate quinol with R-halogen followed by oxidation.
