Beschreibungen/Notizen
The Cover shows a PdII ONO pincer complex that efficiently catalyzes the site‐selective C3‐arylation of N‐methyl‐2‐oxindole with arylboronic acids at room temperature in aqueous media.In their Communication, A. Vignesh et al. demonstrate that this synthesis of 3‐aryl‐N‐methyl‐2‐oxindoles proceeds efficiently with low catalyst loading (0.01 mol %), using two new PdII ONO pincer complexes as homogeneous catalysts. The catalysts showed good compatibility with a wide range of substrates and no appreciable loss of yield was observed in the recyclability tests in up to five consecutive runs.
