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.

Reduction of hydroxy and/or methoxy-substituted isoflavones using LiAlH4 in refluxing THF provides an easy access to a number of α-methyldeoxybenzoins, possible metabolites of phytoestrogens in man. The synthesis of O-demethylangolensin 2b, 6′-hydroxyangolensin 2c, angolensin 2d, 1-(2,4-dihydroxyphenyl)-2-phenylpropan-1-one 2e, 1-(2-hydroxy-4-methoxyphenyl)-2-(4-hydroxyphenyl)propan-1-one2f, 4′-O-methylangolensin 2g, 1-(2-hydroxy-4-methoxyphenyl)-2-phenylpropan-1-one 2h, and 1-(2-hydroxyphenyl)-2-phenylpropan-1-one 2i is described.
