• Preparation of 1,4-hydrobenzoquinones by the PCC/SiO2-promoted double oxidation of 3-cyclohexene-1,2-diols
  作者：Hee Jin Kim、Sangho Koo

  DOI：10.1039/b511067j

  日期：——

  The PCC/SiO2-promoted double oxidation of 3-cyclohexene-1,2-diols, which were easily prepared by the two-step sequence of α′-hydroxylation of various conjugated cyclohexenones and the subsequent nucleophilic carbonyl addition of alkyl anions, produced diversely substituted 1,4-hydrobenzoquinones.

  PCC/SiO2催化的3-环己烯-1,2-二醇的双重氧化反应，经过两步反应序列轻松制备而成：首先是对各种共轭环己烯酮的α'-羟基化，随后是烷基阴离子的亲核碳基添加反应，最终生成了多种取代的1,4-氢苯醌。
