WebThe sulfur analog of an acetal, called a thioacetal, can be produced when a ketone or aldehyde is treated with a thiol (RSH) under acidic conditions. Draw the mechanism for the reaction below. Propane-1,3-dithiol HS SH H. H. A 1,3-dithiane WebThere are quite a few steps in this reaction but fortunately, you don’t need to remember all the steps in order to predict the structure of the aldehyde and ketone of an acetal hydrolysis. Here is the shortcut; draw a line between each oxygen and the carbon they are connected to. These are the bonds that are cleaved during the hydrolysis.

Thioacetals and thioketals can be synthesized by treating aldehydes and ketones with a thiol or dithiol in the presence of an acid catalyst. These functional groups can also be used to protect aldehydes and ketones but are more difficult to hydrolyze. They can be useful in the reduction of aldehydes and ketones. finn corp b40-12
