| '''Reppe chemistry''' refers to a class of ] reactions that are useful in the synthesis of ]s. Classic Reppe reactions include hydrocarboxylation and esterification of ]s, involving the metal-catalysed reaction with ] and ] or ]s.<ref>El Ali, B.; Alper, H.

| The hydrocarboxylation of alkenes is a prominent example of Reppe chemistry. In industry, propanoic acid is mainly produced by the hydrocarboxylation of ] using ] as the catalyst:<ref name=Ullmann>{{ Ullmann | author = W. Bertleff; M. Roeper; X.

| The hydroesterification is similar, but entails the addition of alcohols instead of water, affording esters. | |||
