Synthesis of polyarylated methanes through cross-coupling of tricarbonylchromium-activated benzyllithiums
Support group: Coordinated to the tricarbonylchromium fragment, a typically unstable benzylic organolithium can participate directly in cross-coupling reactions with aryl bromides to form polyarylated methane derivatives (see scheme). Cr(CO)3 assistance leads to reactivity with a variety of coordinated substrates and-given multiple benzylic sites-can effect up to six coupling events per arene. Chemical equation presented
