• Secondary Phosphine Oxides as Multitalented Preligands En Route to the Chemoselective Palladium-Catalyzed Oxidation of Alcohols

  Secondary phosphine oxides O=PHR2 (SPOs) were identified as multitalented preligands for the chemoselective Pd‐catalyzed oxidation of alcohols by a hydrogen‐abstracting methodology. SPOs were found to promote the hydrogen‐abstraction step as well as hydrogen transfer to a Michael acceptor by generating a putative active H−Pd species. The catalytic system operates under neutral conditions and was proven

  通过吸氢方法，仲膦氧化物O = PHR 2（SPOs）被鉴定为化学选择的Pd催化醇氧化的多态预配体。发现SPO通过产生推定的活性H-Pd物种来促进氢的吸收步骤以及氢向迈克尔受体的转移。该催化体系在中性条件下运行，并被证明与底物中的各种亲电子和亲核官能团以及对水和空气敏感的官能团兼容。
