effective and practical modularflowdesign for the meta-selective C-Harylation of anilines. The design consists of four continuous-flow modules (i.e., diaryliodonium salt synthesis, meta-selective C-Harylation, inline copper extraction, and aniline deprotection) which can be operated either individually or consecutively to provide direct access to meta-arylated anilines. With a total residence time
We have developed a heterogeneous catalytic oxidative homocoupling reaction of dimethoxyanilides under an oxygen atmosphere. The resulting homo-dimers are useful for the construction of heterocycles, demonstrating the potential of heterogeneous metal catalysts.

Synthesis of methoxy-2(1H)-quinolonesprecursors of 2-substituted-5,8-quinolinediones is described. A metalation, Heck coupling reaction and cyclisation sequence is used. Regioselectivity of the metalation of methoxypivaloylaminobenzenes is studied.
