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.
