Stereoselective dienyl zirconocene derivatives have been prepared via a tandem allylic C-H bond activation isomerization-elimination reaction. These reagents can be either trapped directly with electrophiles or transmetalated to copper to participate in several carbon-carbon bond formations. When the transmetalation is performed on allylic as well as vinylic zirconocene derivatives, the reaction occurs with inversion of stereochemistry of the dienyl system.
通过串联的烯丙基C-H键活化异构化-消除反应,已经制备了立体选择性的二烯基锆茂衍生物。这些试剂可以直接与亲电试剂捕获,或者通过金属转移至铜上参与多种碳-碳键的形成。当在烯丙基和乙烯基锆茂衍生物上进行金属转移反应时,反应会伴随着二烯体系的立体化学翻转。
