elimination-demanding Pd-catalyzed mono-α-arylation of acetone is demonstrated and reported. The catalyst is tolerant of previously proven challenging electron-deficient aryl chlorides and provides excellent product yields with down to 0.1 mol % Pd. Preliminary investigations suggest that the rate-limiting step for the proposed system is the oxidative addition of aryl chlorides, in which it contradicts
The controllable C2 arylation and C3 diazenylation of indoles with aryltriazenes under ambient conditions was investigated.

A new indolylphosphine WK‐phos has been synthesized for Pd‐catalyzed Suzuki–Miyauracoupling of (hetero)aryl chlorides with (alkyl)arylboronicacids. The catalyst system with this new ligand was found to be highly effective in facilitating the reaction even at catalyst loading levels in the parts per million range (e.g. 10 ppm).
