Trimethylchlorosilane-Mediated Mild -Chlorination of 1,3-Dicarbonyl Compounds Promoted by Phenyliodonium Diacetate

Trimethylchlorosilane was used as chlorine source for the -chlorination of 1,3-dicarbonyl compounds with phenyliodonium diacetate as oxidant at room temperature. The reaction allows the selective synthesis of -monochlorinated products from different kinds of 1,3-dicarbonyl compounds in good yield. The potential possibility of this conversion for bromination has also been investigated.
