An efficient procedure for the oxidation of primary and secondary alcohols to aldehydes and ketones, respectively, with molecular oxygen under ambient conditions has been achieved. By applying catalytic amounts of Pd(OAc)2 in the presence of tertiary phosphine oxides (OPR3) as ligands, a variety of substrates are selectively oxidized without formation of ester byproducts. Spectroscopic investigations
已经实现了在环境条件下用分子氧将伯醇和仲醇分别氧化为醛和酮的有效方法。通过应用催化量的Pd(OAC)的2在叔膦氧化物(OPR的存在3)作为配体,在各种基材的而不形成酯的副产物的选择性氧化。光谱研究和DFT计算表明,氧化膦配体可稳定活性钯(II)催化剂。
