Abstract: Three compounds of a-oxo ketene dithioacetals were prepared by Dieter's method.When 1,2- and 1,3-diiodoalkane in the form of diluted solution were added into the reaction system, four analogues of a-oxo ketene cyclic dithioacetals were obtained in high yields by starting from appropriate a-methylene ketones.

Key words: a-Oxo ketene cyclic dithioacetals, Dilution of halohydrocarbon, Preparation
