Halide exchanged Hoveyda-type complexes in olefin metathesis [PDF]
Beilstein Journal of Organic Chemistry, 2010 The aims of this contribution are to present a straightforward synthesis of 2nd generation Hoveyda-type olefin metathesis catalysts bearing bromo and iodo ligands, and to disclose the subtle influence of the different anionic co-ligands on the catalytic ...

Synergistic approach to polycycles through Suzuki–Miyaura cross coupling and metathesis as key steps
Beilstein Journal of Organic Chemistry, 2018 This account provides an overview of recent work, including our own contribution dealing with Suzuki–Miyaura cross coupling in combination with metathesis (or vice-versa). Several cyclophanes, polycycles, macrocycles, spirocycles, stilbenes, biaryls, and

Cross-Metathesis of an Iron Carbene with Diazenes
Journal of the American
Chemical SocietyOlefin metathesis is one of the most versatile reactions in a synthetic chemist’s toolbox. Metathesis of C=X (X = O, N,(=NR)2) substrates has also been developed; however, the simple cross-metathesis of diazenes and olefins remains unrealized, in part due to the lack of mechanistic information about deactivation pathways for traditional olefin cross ...

New Approaches to Olefin Cross-Metathesis
, 2016 New methodology for the selective cross-metathesis (CM) of terminal olefins employing ruthenium benzylidene 1 is described. CM with symmetric internal olefins was found to provide a useful means for homologating terminal olefins to protected allylic ...
