Simple 2,1-benzisothiazoles, unlike 2,1-benzisoxazoles, do not react with maleic anhydride. 3-Amino-2,1-benzisothiazole reacts to form a maleamic acid; 3-methylamino- and 3-ethylamino-2,1-benzisothiazoles give substituted thioamides, possibly via a Diels–Alder addition product.
与2,1-苯并恶唑不同,简单的2,1-苯并噻唑不与马来酸酐反应。3-氨基-2,1-苯并噻唑反应生成马来酰胺酸;3-甲基氨基-和3-乙基氨基-2,1-苯并噻唑类可能通过Diels-Alder加成产物生成取代的硫代酰胺。
