syn-diacetoxylation of alkenes and 1,2-oxyacetoxylation of terminal alkynes has been developed using (diacetoxyiodo)benzene as oxidant. A broad range of internal and terminal alkenes, including electron-rich as well as electron-deficient alkenes, gave the desired products in good to excellent yields with high diastereoselectivity (up to >99:1 dr). In addition the high catalytic activity of iron catalysis for the
使用(二乙酰氧基碘)苯作为氧化剂,已经开发了铁催化的烯烃的顺式-二乙酰氧基化和末端炔的1,2-氧基乙酰氧基化。各种各样的内部和末端烯烃,包括富电子的和缺电子的烯烃,以高至非对映选择性(高达> 99:1 dr)提供了所需的产物,收率良好至优异。另外,还报道了铁催化末端炔烃的1,2-氧乙酰氧基化的高催化活性。评估了催化剂,氧化剂和其他反应参数对不饱和键活化的作用。
