Cationic Ir complex ([Ir(cod)2]BF4 + BINAP) catalyzed the addition of ortho-C–H bonds in aryl ketones to alkynes, which gave alkenylated products in good to high yield. Styrene derivatives were good substrates, and the enantioselective addition to norbornene was also described.
阳离子Ir络合物([Ir(cod)2 ] BF 4 + BINAP)催化芳基酮中的邻位C-H键加成至炔烃,从而以高收率得到高收率的烯化产物。苯乙烯衍生物是良好的底物,并且还描述了降冰片烯的对映选择性加成。
