Pd(0)-catalyzed 1,1-diarylation of ethylene and allylic carbonates

摘要

An efficient protocol for the one-step synthesis of biologically relevant 1,1-diarylalkanes has been described. This reaction introduces two different aryl groups across the terminal end of simple feedstock alkenes such as ethylene and allylic carbonates. The propensity to generate π-benzylpalladium intermediates dictates the exclusive 1,1-regioselectivity observed in the product.
