Haloketone
In organic chemistry, α-halo ketones can be reduced with loss of the halogen atom to form enolates. The α-halo ketones are readily prepared from ketones by various ketone halogenation reactions, and the products are reactive intermediates that can be used for a variety of other chemical reactions. WebOct 19, 2013 · A simple, mild and convenient method has been developed for the synthesis of 3,4,5-trialkyl-1,3-thiazole-2(3H)-thione derivatives through one pot three-component reaction between a primary amine, carbon disulphide, and α-haloketone in the presence of potassium iodide at room temperature conditions. The products were obtained with …
