Abstract
Commercially available pyridine ligands can significantly enhance the rate, yield, substrate scope, and site selectivity of arene C-H olefination (Fujiwara-Moritani) reactions. The use of a 1:1 ratio of Pd/pyridine proved critical to maximize reaction rates and yields.
摘要
市售的吡啶配体可以显著提高芳基 C-H 烯烃化（Fujiwara-Moritani）反应的速率、产率、底物范围和位点选择性。使用 1:1 的 Pd/吡啶比例对于最大化反应速率和产率至关重要。
