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

This chiral ligand features two diphenylphosphine oxide groups linked by a binaphthalene backbone, offering high rigidity and defined stereochemistry. It delivers predictable coordination geometry in transition metal complexes, enabling efficient asymmetric catalysis. The structure resists oxidation and maintains integrity under standard reaction conditions.

Application

[1,1'-binaphthalene]-2,2'-diylbis(diphenylphosphine oxide) serves as a robust chiral ligand in transition metal catalysis, particularly in asymmetric synthesis. Its rigid binaphthyl backbone and sterically protected phosphine oxide groups enable high enantioselectivity in Pd- and Rh-catalyzed reactions. The compound exhibits excellent bench stability, facilitates easy purification, and demonstrates broad functional group tolerance in cross-coupling and hydrogenation processes.
