hydrogen atmosphere

Ruthenium-Catalyzed Cycloaddition

The_Xelsius_System_380x_380.jpgToday we want to share the following reaction note for the Xelsius system: Selective synthesis of 1,5-disubstituted 1,2,3-triazoles via Azide-Alkyne Cycloaddition (ACC) reaction of benzyl azide and phenylacetylene using Cp*RuCl(PPh3)2 or [Cp*RuCl]4 as catalysts. More than 90% conversion could be achieved under magnetic stirring (700 rpm) for the Cp*RuCl(PPh3)2 catalysed AAC performed in THF at 65°C (30 min). More than 70% conversion could be achieved under magnetic stirring (700 rpm) for the Cp*RuCl4 catalysed AAC performed in DMF at 110°C (30 min).
