Patent

CA 2408329

Phosphine oxide and sulfoxide compounds were used with transition metals, preferably palladium and nickel, to produce biaryls, arylthiols, arylphosphine oxides and arylamines via cross-coupling reactions with aryl halides and arylboronic acids, aryl Grignard reagents, thiols, phosphine oxides or amines.

L'invention se rapporte à l'utilisation de composés d'oxyde de phosphine et de composés sulfoxyde, en association à des métaux de transition, de préférence du palladium et du nickel, aux fins de l'obtention de biaryls, d'arylthiols, d'oxydes d'arylphosphine et d'arylamines par l'intermédiaire de réactions de couplage croisé avec des halogénures d'aryle et des acides arylboroniques, des réactifs aryle de Grignard, des thiols, des oxydes de phosphine ou des amines.
