Abstract

Simple and efficient methods were developed for sp2–sp3 and sp3–sp3 C–C bond-activation reactions of 2-substituted 1,3-diketones. 3-Substituted 3-bromopentane-2,4-diones were deacylated in the presence of an aromatic compound and a silica gel supported ­Brønsted­ acid containing sulfonic groups. The carbocation formed by cleavage of the sp3–sp3 C–C bond of the dione alkylated the aromatic compound.
