XiMo - Olefin Metathesis Highlights

Stereoretentive Catalytic Olefin Metathesis. In Situ Methylene Capping 07. August, 2017 In situ methylene capping: A general strategy for efficient stereoretentive catalytic olefin metathesis is developed using Ru dithiolate catalysts. The concept, methodological implications, and applications to synthesis of biologically active compounds is described.
Stereoselective Catalytic Cross-Metathesis 15. June, 2017 Unsaturated organoboron compounds are important reagents in organic synthesis e.g. (pinacolato)allylboron [allyl-B(pin)] are involved in many stereoselective additions while (pinacolato)vinylboron [alkenyl-B(pin)] reagents are used in various catalytic cross coupling reactions.
Catalytic Ring-Closing Metathesis 02. May, 2017 Catalytic RCM has played a prominent role in connection with the synthesis of macrocyclic alkenes, a structural motif found in an array of biologically active molecules. There is a high demand to develop catalysts that reliably deliver kinetic control of stereoselectivity in the formation of large-ring olefins.
Activation of Oxo Tungsten Complexes 12. April, 2017 The coordination of B(C₆F₅)₃to an oxo ligand in tungsten oxo alkylidene bis(aryloxide) complexes, where the aryloxide is O-2,6-(mesityl) ₂C₆H₃ (HMTO) or 2,6-diadamantyl-4-methylphenoxide (dAdPO), accelerates the formation of metallacyclobutane complexes from alkylidenes as well as the rearrangement of metallacyclobutane complexes.

Ring-Opening Metathesis Polymerization

30. March, 2017

It has been shown that Z-selective reactions in ROMP have some generality and that syndiotacticity (for cis polymers) is predictable as a consequence of the mechanism through which MAP catalysts operate, i.e., inversion of configuration at the metal center with each forward metathesis step (stereogenic metal control).
