Reactivity of Ketones

Do ketones react with thio alcohols?

I was studying the protection of carbonyls through acetals, and in my notes, I'd written down that ketones don't react with monohydric alcohols. Do they react with thio alcohols?

Ketones do indeed react with alcohols. The product is a ketal under acidic conditions. Thiols react as well to produce thioketals. One protection group for ketones is 1,3-dithiopropane. The cyclic thioketal is the protected group stable to base and easily removed by acid.
