Abstract
In situ formation of heterobimetallic Pt-Ti catalysts enables rapid room temperature catalysis in enyne cycloisomerization reactions. The Lewis acidic titanium atom in the ligand framework is shown to be essential for fast catalysis. A range of enyne substrates are efficiently cyclized to carbocycles and heterocycles in high yield.
摘要
异双金属铂 - 钛催化剂的原位形成能够在烯炔环异构化反应中实现快速室温催化。配体框架中的路易斯酸性钛原子被证明对快速催化至关重要。一系列烯炔底物能够高效地环化生成碳环和杂环，产率很高。
