  末端炔烃和烯基异氰酸酯的对映选择性铑催化 [2 + 2 + 2] 环加成：机理洞察导致统一模型，使产品选择性合理化

  摘要：

  这份手稿描述了末端炔烃和烯基异氰酸酯的不对称铑催化 [2 + 2 + 2] 环加成反应的发展和范围，导致形成吲哚里西啶和喹尼西啶支架。亚磷酰胺配体的使用证明对于避免竞争性末端炔二聚化至关重要。脂肪族和芳香族末端炔烃都能很好地参与，产物选择性与炔烃的空间和电子特性有关。亚磷酰胺配体的操纵导致对映选择性和产物选择性的调整，当从基于 Taddol 的亚磷酰胺转移到基于双酚的亚磷酰胺时，脂肪族炔烃可以看到产物选择性的完全转变。末端和 1,1-二取代烯烃的耐受性几乎相同。一系列竞争实验的检查与反应结果的分析相结合，为操作催化循环提供了相当多的启示。通过对氯化铑（鳕鱼）/亚磷酰胺配合物的一系列 X 射线结构的详细研究，我们制定了一个机械假设，使观察到的产品选择性合理化。

  Novel stress-reducing crosslinking oligomers that have application in dental restoratives, thin films, hardcoats, composites, adhesives, and other uses subject to stress reduction are described. The addition-fragmentation process of crosslinking results in a chain-transfer event that provides novel polymers that may be further functionalized. In addition, the addition-fragmentation oligomer comprises pendent functional groups that bond to a substrate by forming an ionic or covalent bond, or etch the substrate by chemically removing some material from the substrate.
