6.5 Oxidation of Alchols
Alkenes react with mercuric acetate in a mixture of water and tetrahydrofuran (THF) to produce (hydroxyalkyl) mercury compounds. These can be reduced to alcohols with sodium borohydride and water.
(a) Oxymercuration
(b) Demercuration
The net addition of $H—$ and $—OH$ takes place with Markovnikov regioselectivity and takes place without the complications of rearrangements.
