Abstract:A facile method for the preparation of 10 arylmethylene anthrone is reported.When anthrone react with aryl aldehyde in the presence of pyridine by using xylene as the solvent,besides 10 arylmethylene anthrone derivatives we found other oxygenated anthrone which have not been reported.Physical methods shows that the oxygenated anthrone is anthraquinone,and the anthraquinone cannot be removed from the condensed products by recrystallization with solvents.An effective method of getting ride of anthraquinone is sublimation by heating.
