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

Trimethylchlorosilane was used as chlorine source for the α-chlorination of 1,3-dicarbonyl compounds with phenyliodonium diacetate as oxidant at room temperature. The reaction allows the selective synthesis of α-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.

A Useful Synthesis of 3-Halogeno-1-azabutadiene Derivatives, and Their Applicability in the Preparation of Heterocycles

Azabutadiene derivatives (1) are halogenated in a selective manner with N-chlorosuccinimide or N-bromosuccinimide at the Cβ-enamine carbon.The resultant halogenated compounds (3) are suitable precursors for the synthesis of 2-oxopyrimidines and
