In 2007, a new class of carbenes, namely cyclic (alkyl) (amino) carbenes (CAACs), emerged as a competitor to NHCs as ligands for olefin metathesis catalysts. Since then, CAACs have been intensively studied, demonstrating exceptional productivity in ethenolysis processes (Turnover number up to 2.6 million at 100 ppb catalyst loading) while achieving remarkable catalytic performances in a number of other metathesis transformations. Despite these impressive results, the use of CAAC ligands in asymmetric catalysis is still in its infancy. This lecture will present pioneering developments in optically pure CAAC-Ruthenium complexes and their evaluation in asymmetric olefin metathesis. Additionally, thanks to density functional theory models, mechanistic insights highlighting the origin of enantioselectivity will also be discussed.
