A number of diversely substituted furans are synthesized via a cycloisomerization process that goes through a unique metal carbene species. Both ligand structure and the nature of the leaving group are evaluated. The characteristics of the carbene intermediate can be modulated, resulting in highly selective hydrogen or silicon group migrations.
通过独特的金属卡宾物种经历的环异构化过程,合成了许多取代基不同的呋喃。评估了配体结构和离去基团的性质。卡宾中间体的特性可以进行调节,从而导致高度选择性的氢或硅基团迁移。
