The cationic ruthenium hydride complex [(C6H6)(PCy3)(CO)RuH]+BF4- has been found to be an effective catalyst for the oxidative C-H coupling reaction of phenols with aldehydes to give 2-acylphenol compounds. The coupling of phenols with α,β-unsaturated aldehydes selectively gives the flavene derivatives. The catalytic method mediates direct oxidative C-H coupling of phenol and aldehyde substrates without using any metal oxidants or forming wasteful byproducts. A cationic ruthenium hydride complex catalyzes the oxidative C-H coupling of phenols with aldehydes to form 2-acylphenol and flavene derivatives.

Methylation of four different 2-hydroxydesoxybenzoins ( 1a, 1c, 1d, 1f) separately with methyl iodide in the presence of dry potassium carbonate and acetone at 35-40 deg C affords both C-methyl-(2a, 2d) and O-methyl-(1b, 1e) derivatives.However, 1a provid
