Abstract
A method for preparing benzyl alcohols or substituted benzyl alcohols is disclosed by decarbonylation of formic acid esters of benzyl alcohols or ring substituted benzyl alcohols, the decarbonylation being carried out in the presence of a catalyst.
Claims32
A method for preparing a benzyl alcohol or ring-substituted benzyl alcohol which comprises decarbonylating a formic acid ester of the corresponding benzyl alcohol in the presence of 0.01 to 15 mol percent of a strong base as catalyst by heating at a temperature sufficient to effect carbon monoxide evolution said formic acid ester in the presence of said strong base in a reaction mixture consisting essentially of said formic acid ester and said catalyst, the process being carried out either in the melt or in the presence of a solvent, the solvent being a tertiary alcohol or an alcohol corresponding to the formic acid ester reactant, the decarbonylation being carried out at a temperature at which the formic acid ester employed and the resulting alcohol are in fluid form.
