Barton Decarboxylation - Organic Chemistry

Mechanism of the Barton Decarboxylation. The initiation of the Barton Decarboxylation ( Bu 3 Sn-H - Bu 3 Sn.) is effected with a radical initiator, and as with the Barton-McCombie Deoxygenation, the driving force for the reaction itself is the formation of the stable S-Sn bond. In addition, Barton esters can also be cleaved photolytically or thermally:
