Abstract
A dehydrogenative reaction of primary alcohols in the presence of hydroxide and the ruthenium complex [RuCl2(IPr)(p-cymene)] as catalyst provides carboxylic acids. The use of toluene enables a simple product isolation by precipitation and extraction. A range of benzylic and saturated aliphatic alcohols containing halide and (thio)ether substituents can be converted, while olefins and ester groups are not compatible.
