The Wacker reaction is one of the longest known palladium-catalysed organic transformations, and in the vast majority of cases proceeds with Markovnikov regioselectivity. Palladium(II)-mediated oxidation of styrenes was examined and in the absence of reoxidants was found to proceed in an anti-Markovnikov sense, giving aldehydes. Studies on the mechanism of this unusual transformation were carried out
Wacker反应是已知的最长的钯催化的有机转化之一,在大多数情况下,马尔可夫尼可夫区域选择性会继续进行。检查了钯(II)介导的苯乙烯氧化,发现在没有再氧化剂的情况下,其以反马尔科夫尼科夫意义进行,产生醛。对这种异常转化的机理进行了研究,并指出了可能与eta(4)-钯-苯乙烯复合物有关。用杂多酸作为末端氧化剂,发现苯乙烯的氧化得到主要的反马尔科夫尼科夫醛是催化性的。
