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