An efficient method for the synthesis of ketones using organolithium and acid chlorides under continuousflow conditions has been developed. In contrast to standard batch chemistry, over-addition of the organolithium to the ketone for the formation of the undesired tertiary alcohol has been minimised representing a direct approach toward ketones.

Direct functionalization of inert C(sp3)-H bonds in pharmaceutically significant compounds is very important in modern synthetic organic chemistry. In this article, we disclose a practical and efficient method for the oxidative lactonization of benzylic C(sp3)-H bonds enabled by the synergistic interactions of organic dye-type rose bengal, n-Bu4N·Br, O2 and Na2HPO4 under visible light irradiation.
