Mild, efficient, and clean! Six‐membered cyclic products including diiodocyclohexadiene and 2,3‐diiodobenzene have been prepared in a iodonium‐induced internal carbocyclization of hydroxylated enynes (see scheme). This reaction proceeds smoothly under mild reaction conditions, and all the halogen atoms (I and Br) generated from the electrophiles are used effectively.
温和,高效,清洁!六元环状产物,包括二碘代环己二烯和2,3-二碘代苯,是在碘鎓诱导的羟基烯炔的内部碳环化反应中制备的(参见方案)。该反应在温和的反应条件下平稳进行,并且有效利用了由亲电试剂产生的所有卤素原子(I和Br)。
