Protoboration of Alkynes and Miyaura Borylation Catalyzed by Low Loadings of Palladium.

ABSTRACT

The versions of Miyaura borylation and protoboration of alkynes catalyzed by low loadings of palladium (400 mol ppm = 0.04 mol %) have been developed. These transformations have a broad substrate scope, good functional-group compatibility, and gram-scale synthetic ability.
