Reactivity Change of Cyclobutanols towards Isocyanates: Rhodium Favors <i>C</i>‐Carbamoylation over <i>O</i>‐Carbamoylation

Abstract

Umgekehrt: In Gegenwart bzw. Abwesenheit eines Rhodium-Katalysators wurden bei der Addition von Cyclobutanolen an Isocyanate gegensätzliche Reaktionswege beobachtet: Bloßes Erhitzen führte zu einer direkten O-Carbamoylierung und somit zu Cyclobutylcarbamaten. Die Hinzugabe eines Rhodium-Katalysators ermöglichte hingegen eine C-Carbamoylierung durch eine Ringöffnungsreaktion.
