Abstract: Sulfur-chelated ruthenium olefin metathesis precatalysts that possess cyclic (alkyl)(amino)carbenes (CAAC) can benefit from the synergetic effect of both ligands. Changing the steric bulk of the CAAC ligand by using different substitution patterns was shown to… read more here.

Abstract: Ruthenium alkylidene complexes are prepared via enyne ring-closing metathesis relying on the exo and endo gem-dialkyl substituent effect. The structural features stabilizing oxygen-chelates are explored and confirmed by single crystal X-ray diffraction analyses. In stark… read more here.
