Stars This … Pivalic acid is a key intermediate for the target molecules which require hydrolytic stability and a variety of chemical resistance. Pivalic acid is used mainly in the form of chloride salt (pivaloyl chloride) which is obtained commercially from phosgene. The comproportionation reaction between Mn(II) and Mn(VII) reagents under acidic conditions has been investigated in the presence of pivalic acid as a route to new high oxidation state manganese pivalate clusters containing some Mn(IV).
