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 concentration up to 1.0 M with the medium being recycled up to ten runs without any loss of catalytic activity.

在温和的台式条件下，深共晶溶剂催化的炔丙醇的迈尔-舒斯特重排

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。
