    Carbonyl rhenium(I) complexes are efficient catalysts for the regioselective isomerization of terminal propargylic alcohols into α,β-unsaturated aldehydes or ketones which can be used as an unprecedented recyclable catalytic system (up to 10 consecutive runs) in the ionic liquid [BMIM][PF6].
    羰基铼(I)配合物作为催化剂,能够高效地选择性异构化末端炔丙醇为α,β-不饱和醛或酮,这种催化体系前所未有地可在离子液体[BMIM][PF6]中循环使用(多达10次连续运行)。
  • Deep eutectic solvent-catalyzed Meyer–Schuster rearrangement of propargylic alcohols under mild and bench reaction conditions

    The Meyer–Schuster rearrangement of propargylic alcohols into α,β-unsaturated carbonyl compounds has been revisited by setting up an atom-economic process catalyzed by a deep eutectic solvent FeCl3·6H2O/glycerol. Isomerizations take place smoothly, at room temperature, under air and with short reaction times. The unique solubilizing properties of the eutectic mixture enabled the use of a substrate
    通过建立由低共熔溶剂FeCl 3 ·6H 2 O /甘油催化的原子经济过程,重新探讨了炔丙醇向α,β-不饱和羰基化合物的Meyer-Schuster重排。异构化可在室温,空气,短反应时间内平稳进行。低共熔混合物独特的增溶性能使其能够使用浓度高达1.0 M的底物,并且将介质循环使用多达十次,而不会损失任何催化活性。

    The behavior of 3,4-dimethyl-1-pentyn-3-ol (II) and 3-isopropyl-4-methyl-1-pentyn-3-ol (III) toward formic acid was investigated. The carbinols, as in the previous report, were chosen as model ones in which the tertiary carbon atom is adjacent to the carbon atom carrying the hydroxyl group. Both carbinols gave a significant quantity of the respective aldehydes. These aldehydes were easily isolated
    研究了 3,4-二甲基-1-戊炔-3-醇 (II) 和 3-异丙基-4-甲基-1-戊炔-3-醇 (III) 对甲酸的行为。与之前的报告一样,甲醇被选为模型,其中叔碳原子与携带羟基的碳原子相邻。两种甲醇都产生大量相应的醛。这些醛很容易通过简单的蒸馏分离出来。II 以 45% 的产率得到 3,4-二甲基-3-戊烯-2-酮 (IIa),以 5% 的产率得到 3,4-二甲基-2-戊烯醛 (lib),一种新的醛。III以55%的产率得到3-异丙基-4-甲基-3-戊烯-2-酮(IIIa)和以6%的产率得到3-异丙基-4-甲基-2-戊烯醛(IIIb)。表征了这些羰基化合物。IIIb被氢化得到3-异丙基-4-甲基戊醛(IV),为2,4-二硝基苯腙。
