HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

4,6-Bis(diphenylphosphino)dibenzofuran is a sterically hindered, electron-rich phosphine ligand featuring two diphenylphosphino groups at the 4 and 6 positions of a dibenzofuran core. This rigid, planar architecture enhances metal coordination stability and promotes efficient catalytic turnover in palladium- and nickel-catalyzed cross-coupling reactions. The ligand exhibits excellent thermal and air stability under standard handling conditions, enabling robust performance in demanding synthetic workflows.

Application

4,6-Bis(diphenylphosphino)dibenzofuran serves as a highly effective, bench-stable ligand in palladium-catalyzed cross-coupling reactions. Its rigid dibenzofuran backbone enhances electron density and steric control at the phosphine centers, enabling efficient coupling of challenging substrates such as aryl chlorides and heteroaryl halides. The ligand demonstrates broad functional group tolerance and facilitates catalyst turnover in Suzuki, Stille, and Negishi reactions, making it a reliable choice for complex molecule synthesis and process-scale applications.
