  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。

  Abstract13C NMR spectra of thiols, sulfinic acids, sulfinyl chlorides, sulfonic acids and sulfonic anhydrides have been obtained. The data are discussed in terms of the additivity of the deshielding effects exerted by the sulfur functionality at the α‐ or β‐position, and the shielding effects produced by the sulfur function at the γ‐position.
