XiMo - Olefin Metathesis Highlights

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.
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.
Efficient Synthesis of Metathesis Catalysts 07. March, 2017 Despite the lack of literature precedents, Mo and W based metathesis catalysts excel in extreme low catalyst loadings. Feedstock quality granted loadings of 6 – 50 ppm (by mole) are common.
