Abstract
The present invention relates to a method of preparing ortho substituted phenols from 2,5-dimethylfuran and propargyl ethers in the presence of a gold(I) complex. It is particularly advantageous to use 2,5-dimethylfuran as this offers an ecological beneficial synthesis of said ortho substituted phenols.
