Facile deoxygenation of phenols and enols using sodium borohydride–nickel chloride
Abstract
A facile deoxygenation reaction of phenol and 1,3-dicarbonyl compounds was investigated. Phenols, enolizable 1,3-diketones and 3-ketoesters were converted into the toluene-p-sulfonates which were reduced by a sodium borohydride–nickel chloride system to give the deoxygenated aromatic compounds, alcohols and esters, respectively.
