Almabor ® TPB

This high-purity organoborate is a Lewis acid which acts as a reaction rate accelerator in polycarbonate polymerization by enhancing the electrophilicity of the carbonyl group. It can be used as a catalyst for multicomponent aziridation of aldehydes, asymmetric aziridation of imines, Hetero-Diels-Alder reactions and Mukaiyama aldol condensation, asymmetric Claisen rearrangement of unactivated allyl vinyl ethers, and the cross-metathesis of alkenes with 3-nitropropene.
