摘要：

Preparative methods for the two titled compounds by the reaction of SF4 with dichloromaleic anhydride and dichloromaleic acid are reported. Prior synthesis of the tetrafluoro compound using the anhydride is better defined and improved by use of the acid. The tetrafluoro compound is an intermediate for the synthesis of tetrafluorooxydiacetic acid, which is an important intermediate in exploratory polymer synthesis. © 1969, American Chemical Society.
