Bis(neopentyl glycolato)diboron Structural

What is Bis(neopentyl glycolato)diboron?

Description

Bis(neopenyl glycolato)diboron is a boronating agent which provides the corresponding boronate ester via Pd-catalyzed coupling, similar to bis(pinacolato)diboron. Bis(neopenyl glycolato)diboron has been found to be more efficient than bis(pinacolato)diboron for the synthesis of hindered ortho-substituted arylboronic acids. Neopentylato boronic esters are more readily hydrolyzed to boronic acids than their corresponding pinacolato esters.
