CF and CH Bond Activation Reactions of Fluorinated Molecules at Rhodium Pincer Complexes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
Hydrido Rh pincer complexes showed C–F bond activation reactivity with a selectivity at the para position of pentafluoropyridine and octafluorotoluene. The C–H bond activation capability was unleashed by irradiation with UV light to obtain a deprotonated and coordinative unsaturated pincer complex intermediate as the active species.

Ringspannungs‐vermittelte Aktivierung von Pyridinen durch einen gesättigten BSi2‐Ring

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Wir berichten über ein stark gespanntes Boratadisiliran mit dem bisher nicht zugänglichen anionischen BSi2‐Ringmotiv. Die Spaltung der S–Si‐Bindung während der Reaktionen mit Pyridinderivate aktiviert diese auf drei verschiedene Arten: (1) Bei Pyridin selbst erfolgt eine selektive ortho‐CH‐Aktivierung und ein gleichzeitiger Wasserstofftransfer zu einem
