Rac-binap是什么

BINAP (2,2′-bis(diphenylphosphino)-1,1′-binaphthyl) is an organophosphorus compound. This chiral diphosphine ligand is widely used in asymmetric synthesis. It consists of a pair of 2-diphenylphosphinonaphthyl groups linked at the 1 and 1′ positions. This C2-symmetric framework lacks a stereogenic atom, but has axial chirality due to restricted rotation (atropisomerism). The barrier to racemization is … TīmeklisBINAP. بی آی ان ای پی ( به انگلیسی: BINAP ) با فرمول شیمیایی C44H32P2 یک ترکیب شیمیایی است. که جرم مولی آن ۶۲۲٫۶۷ گرم بر مول می باشد. شکل ظاهری این ترکیب، جامد بی رنگ است. 22' - Bis ( diphenylphosphino ) - 11' - binaphthyl
