Iron-catalysed chemo-and: Ortho-selective C-H bond functionalization of phenols with α-Aryl-α-diazoacetates

Herein we present a novel iron-catalyzed chemo-and regio-selective ortho C-H bond functionalization of phenols and naphthols with diazo compounds. In this transformation, an iron porphyrin exhibits specific catalytic activity, and is quite different from the commonly used precious metal catalysts.
