Abstract

coupling - ultimately yielding a Mo(vi) metallacyclopropane complex, 5. Addition of multiple equivalents of isocyanate instead interrupts this mechanism, leading to C-N and C-O bonds cleavage and the formation of aminocarbyne and imido ligands bridging the Ir and Mo centers, along with a molybdenum(vi)-oxo moiety. This unprecedented reactivity, mediated by a key reaction intermediate featuring an unsupported Mo-Ir quadruple bond, illustrates the interest of heterobimetallic compounds for complex bond activation and reorganization.
