Performance of SCS Palladium Pincer Complexes inBorylation of Allylic Alcohols. Control of theRegioselectivity in the One-Pot Borylation-Allylation Process

摘要

One-pot borylation-allylation reactions of aldehydesand allylic alcohols were performed under various react-ion conditions. The borylation of allylic alcohols wasperformed using a very efficient SCS palladium pincer-complex catalyst. The regioselectivity of the allylationdepends on the applied solvent. The reaction in CHCl_3gave the linear allylic product; however, when Me0H wasadded to the reaction mixture, the branched allylic prod-uct was formed.
