Sulfonamide-Trapping Reactions of Thermally Generated Benzynes

, 2018
Reactions of tethered, tertiary sulfonamides with thermally generated benzynes are reported. Typically, the N–S bonds in the substrates cleave, and saturated heterocycles [tetrahydroquinolines (n = 2) and indolines (n = 1)] are formed.

Katalysatoraktivierung als Schlüsselfaktor in Kreuzkupplungen: Raumtemperatur‐Kupplungen schwacher Nukleophile ermöglicht durch [Pd(1‐MeNAP)TFA]2 Präkatalysatoren

Angewandte Chemie, EarlyView.
Bei vielen Pd‐katalysierten Kreuzkupplungen hat sich gezeigt, dass die Katalysatorleistung durch dessen Aktivierung begrenzt wird. Methylnaphthyl (MeNAP)‐Palladiumtrifluoracetat‐Dimere werden als leicht zu lagernde und handhabende Präkatalysatoren vorgestellt, die sich unter Reaktionsbedingungen schnell aktivieren, selbst wenn nur schwach ...
