Cationic Fe complexes of the general type [(Ph3P)2Fe(CO)(NO)]X (X=BF4, BArF4) catalyze the redox‐neutral cycloisomerization of 1,6‐ and 1,7‐enyneacetates to afford bicyclic cyclobutanes under mild conditions in good yields and diastereoselectivities.
一般类型的阳离子型铁配合物[(Ph 3 P)2 Fe(CO)(NO)] X(X = BF 4,BAr F 4)催化1,6-和1,7-烯炔乙酸酯的氧化还原-中性环异构化在温和条件下以良好的收率和非对映选择性提供双环环丁烷。
