Application
Be used as pharmaceutical intermediate.
The bis-pinacol borate is a boron compound containing two pinacol structures. This compound is a commercially available reagent and is a commonly used substrate in organic synthesis for the preparation of various pinacol borate esters.
Cis-complex boronation reagent for acetylene and paraffin (platinum catalysis).
Palladium catalyzed boronation of aromatic compounds.
Palladium-catalyzed cyclization of 1,6-enyne produces a substrate in the reaction of homogeneously alkylboronates.
 
Package: 25kg/drum, can also be designed according to customer requirements.
