diasteroselective and enantioselective Ir-catalyzed allylic substitutions of 1-substituted 1-fluoro-1-(arenesulfonyl)methylene derivatives are presented, which afford the fluorinated allyl products with two chirality centers. The steric demand of 1-substituted 1-fluoro-1-(arenesulfonyl)methylene derivatives and allylic substrates has a great influence on the dr values of these reactions. The transformation of the branched allyl product into the fluorinated 3,4-dihydro-2H-pyrrole 1-oxide was discussed, as well.

1-取代的1-氟-1-（芳烃磺酰基）亚甲基衍生物的非对映选择性和对映选择性Ir催化的烯丙基取代

提出了1-取代的1-氟-1-（芳烃磺酰基）亚甲基衍生物的非对映选择性和对映选择性Ir催化的烯丙基取代，其提供了具有两个手性中心的氟化烯丙基产物。1-取代的1-氟-1-（芳烃磺酰基）亚甲基衍生物和烯丙基底物的空间需求对这些反应的dr值有很大影响。还讨论了支链烯丙基产物向氟化的3，4-二氢-2 H-吡咯1-氧化物的转化。
