The adducts between ketones and the anion derived from [(methoxymethyl)sulfonyl]benzene undergo efficient, regioselective rearrangement to give α-methoxyketones when treated with ZrCl4 and HfCl4; this new procedure allows the sulfone-mediated homologation methodology to be applied to monocyclic and acyclic ketones.
酮与源自[(甲氧基甲基)磺酰]苯的阴离子之间的加成物在与ZrCl4和HfCl4反应时,发生有效的区域选择性重排,生成α-甲氧基酮;这一新步骤使得以磺酰为媒介的同源化方法可以应用于单环和链状
酮类化合物。
