Thioaldehydes, Thioketones, and Thioacetals
Thioacetals Rule C-533 533.1 - Sulfur analogues of acetals, namely, those containing the group or are named
substitutively by the use of the prefixes "alkylthio-" and "alkyloxy-", "arylthio-" and "aryloxy-", etc. Such compounds are known generically as "dithioacetals" and "monothioacetals",
respectively, but these names are not used for systematic nomenclature except in certain specialized fields such as that of the carbohydrates.
533.2 - Monothiohemiacetals are named as alcohols substituted by a group -SR; monothiohemiacetals are named as thiols substituted by a group -OR.
