A catalytic system has been developed for the efficient synthesis of tertiary arylphosphine oxides by coupling of readily available secondary phosphine oxides with aryl bromides or iodides in the presence of copper(I) iodide as a catalyst and (S)-α-phenylethylamine as a ligand. The system exhibits high activity in the coupling of secondary diaryl-, alkylaryl- and dialkylphosphine oxides.
已经开发了一种催化体系,用于在碘化铜(I)和配体(S)-α-苯乙胺存在下,通过将易得的仲膦氧化物与芳基溴化物或碘化物偶合,有效地合成叔芳基膦氧化物。。该体系在仲二芳基-,烷基芳基-和二烷基膦氧化物的偶联中表现出高活性。
