(Chemical Equation Presented) Efficient cross-coupling, allowing a straightforward access to congested benzophenones, between aromatic aldehydes and potassium aryltrifluoroborates, is described in the presence of a rhodium/tri-tert-butylphosphane catalyst system and acetone as cosolvent. The use of the stable phosphonium salts of tri-tert-butylphosphane prevented the use of highly oxidizable tri-tert-butylphosphane and allowed a careful control of the stoichiometry with the rhodium.
