In organosulfur chemistry, thioacetals are the sulfur (thio-) analogues of acetals (R−CH(−OR)2). There are two classes: the less-common monothioacetals, with the formula R−CH(−OR')−SR", and the dithioacetals, with the formula R−CH(−SR')2 (symmetric dithioacetals) or R−CH(−SR')−SR" (asymmetric dithioacetals). WebThial.
