palladium-catalysed cross-couplingreactions has been developed. The extent of aromatic iodination is controlled by stoichiometry and affords either the mono-, di- or tri-iodo-cardanol derivatives. Suzuki, Heck and Sonogashira protocols were successfully applied for the vinylation, arylation and alkynylation of the iodo-cardanols. 2,4-Diiodo-5-n-pentadecylphenol underwent an unusual sequential regioselective deha
