  The present invention is directed to provide an efficient production method which is capable of not only obtaining a cyclic sulfonic acid ester (sultone) at low cost and in high yield, but also the sulfonic acid ester (sultone) stably even in a commercial scale. The present invention relates to a method for producing hydroxysultone comprising a first step where a diol having a specified structure and a thionyl halide are reacted to obtain a cyclic sulfite having a specified structure, and a second step where the cyclic sulfite is reacted with water or/and alcohol; a method for producing an unsaturated sultone having a specified structure comprising a third step where a hydroxylsultone having a specified structure is reacted with an acid halide or an acid anhydride to obtain an intermediate, subsequently the intermediate is treated with a base; as well as a cyclic sulfite having a specified structure.

  本发明旨在提供一种高效的生产方法，该方法不仅能够以低成本和高产率获得环状磺酸酯（磺酮），而且能够在商业规模下稳定地生产磺酸酯（磺酮）。本发明涉及一种生产羟基磺酮的方法，包括第一步，其中将具有特定结构的二元醇和硫酰卤反应，以获得具有特定结构的环状亚磺酸酯，以及第二步，其中将环状亚磺酸酯与水或/和醇反应；一种生产具有特定结构的不饱和磺酮的方法，包括第三步，其中将具有特定结构的羟基磺酮与酸卤或酸酐反应，以获得中间体，随后用碱处理中间体；以及具有特定结构的环状亚磺酸酯。
