| | 3-BENZYL-5-(2-HYDROXYETHYL)-4-METHYLTHIAZOLIUM CHLORIDE Usage And Synthesis |
| Uses | 3-Benzyl-5-(2-hydroxyethyl)-4-methylthiazolium chloride, aliphatic aldehydes undergo the acyloin condensation in the presence of this catalyst and mild base. It acts as a catalyst for the addition of aliphatic and heterocyclic aldehydes to α,β-unsaturated ketones, nitriles and esters. | | Purification Methods | Purify the chloride by recrystallisation from EtOH or H2O. If placed in a bath at 125o and heated at 2o/minute, the melting point is 140.5-141.4o.
