Control experiments showed that the selectivity of this reaction was exclusively controlled by the temperature. It was possible to generate a variety of 2,2\u2032\u2010biflavanones bearing different substitution patterns at the aromatic ring in good\u2010to\u2010quantitative yields, being both stereoisomers of the desired compounds obtained with total or high control of selectivity. A mechanism that explains both the generation of the corresponding 2,2\u2032\u2010biflavanones and the selectivity is also discussed.
