The conjugate base of a thiol is called a thiolate. Butanethiol has a pK a of 10.5 vs 15 for butanol. Thiophenol has a pK a of 6, versus 10 for phenol. A highly acidic thiol is pentafluorothiophenol (C 6 F 5 SH) with a pK a of 2.68. Thus, thiolates can be obtained from thiols by treatment with alkali metal hydroxides.
