A new chiral catalyst for olefin metathesis is prepared from commercially available materials and is equally or more effective and selective than the previous systems. The new user-friendly catalyst can be prepared in situ (see scheme, Ar=aryl, Tf=trifluoromethanesulfonyl), isolation not needed, outside of a glove box, and delivers reactivity and enantioselectivity levels formerly available only through
无需杂物箱!一种新的用于烯烃复分解的手性催化剂是由可商购的材料制备的,并且与先前的系统相比具有同等或更有效和选择性。新的用户友好型催化剂可在手套箱外部原位制备(见方案,Ar =芳基,Tf =三氟甲磺酰基),无需分离,并提供以前只能通过多种催化剂才能获得的反应性和对映选择性。
