In the realm of homogeneous catalysis, the ligand plays a crucial role in dictating the efficiency, selectivity, and overall success of a chemical transformation. Among the plethora of available ligands, diphosphines stand out for their ability to chelate metal centers, offering enhanced stability and control. One such exceptional ligand is Xantphos, known scientifically as (9,9-Dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine), with the CAS number 161265-03-8.

Xantphos is distinguished by its unique structural feature: a wide bite angle, typically around 108°. This characteristic geometry arises from its xanthene backbone, which provides a relatively rigid yet flexible scaffold. This wide bite angle is instrumental in influencing the coordination sphere around the metal catalyst, often promoting specific reaction pathways and leading to improved outcomes in catalytic processes.

Our commitment is to provide researchers and industrial chemists with high-purity Xantphos, ensuring consistent and reliable performance in their catalytic applications. We offer competitive Xantphos cost and a stable supply chain, making us a preferred partner for sourcing this vital chemical intermediate.

The utility of Xantphos spans a broad spectrum of metal-catalyzed reactions. It is particularly renowned for its efficacy in palladium-catalyzed cross-coupling reactions, such as the Buchwald-Hartwig amination and Suzuki-Miyaura coupling. In these reactions, Xantphos facilitates the formation of new carbon-nitrogen and carbon-carbon bonds, which are fundamental to the synthesis of pharmaceuticals, agrochemicals, and advanced materials. Its ability to stabilize catalytic intermediates and promote key elementary steps, like reductive elimination, contributes significantly to higher yields and cleaner reaction profiles.

Furthermore, Xantphos is a vital ligand in rhodium-catalyzed hydroformylation. This process, crucial for the production of aldehydes from alkenes, relies heavily on the ligand’s ability to control regioselectivity, favoring the formation of linear aldehydes. The wide bite angle of Xantphos often leads to enhanced linearity and activity in these systems.

Beyond these prominent examples, Xantphos finds application in hydrocyanation, C–X bond formations, and a multitude of other catalytic cycles involving transition metals like nickel, platinum, copper, and ruthenium. Its versatility makes it an invaluable tool for chemists exploring novel synthetic routes and optimizing existing catalytic processes.
