A metal-free CÀ P bond cleavage reaction is described herein. Phosphoramides, a phosphine source, can react with alcohols to produce phosphonate and phosphinate derivatives in the presence of a disulfide. PÀ H 2 , P-alkyl, and P,P-dialkyl phosphoramides can be used as substrates to obtain the corresponding pentavalent phosphine products.

An environmentally friendly oxone (20 mol%) catalyzed esterification of carboxylic acids with alcohols has been developed, providing an attractive alternative to the construction of valuable carbonyl esters.
