the oxo-metal-catalyzed deoxydehydration of diols and polyols to produce olefins and the corresponding arenes. NH4ReO4 and MeReO3 are active catalysts for the reactions. The most effective of the hydroaromatic reductants is indoline, which is oxidized to indole. Yields for a variety of diols and polyols range from 35% to 99%. Two hydrogen donors, 1,3-cyclohexadiene and dihydroanthracene, engage in tandem
在二醇和多元醇的羰基金属催化的脱氧脱水中,几种二氢芳族化合物被证明是有效的还原剂,以生产烯烃和相应的芳烃。NH 4 ReO 4和MeReO 3是反应的活性催化剂。最有效的加氢芳族还原剂是二氢吲哚,其被氧化成吲哚。各种二醇和多元醇的产率为35%至99%。两个氢供体,1,3-环己二烯和二氢蒽,参与串联的DODH /环加成反应。竞争实验表明,吲哚啉在H转移中比代表性醇更具反应性。显示吲哚啉通过可分离的加合物MeReO 3将MeReO 3还原为MeReO 2(二氢吲哚)(4),其已经在结构上进行了表征,并被认为是催化DODH过程的中间体。
