A SH-selective allylation method using [CpRu(2-quinolinecarboxylato)(η3-C3H5)]PF6 has been realized in various solvents including aqueous media to give allyl sulfides and allyl S-thioates, demonstrating the potential applicability to lipopeptide chemistry.

Palladium(II) salts catalyze the Kirmse reaction of allylsulfides with trimethylsilyldiazomethane (TMSD) to give homoallylsulfides. Similarly, TMSD can intercept ArPdX intermediates generated during Stille couplings to give benzhydryl derivatives. The yields of this process are limited by overinsertion and β-elimination. Insertion and elimination can be harnessed to generate styrenes from benzylic
