Efficient one-step syntheses of α,β- and β,β-dihaloenones were achieved by ruthenium(II)- catalyzed reactions between cyclic or acyclic diazodicarbonyl compounds and oxalyl chloride or oxalyl bromide in moderate to good yields. This methodology offers sev

The present invention relates to a method for preparing andalpha;,andbeta;- or andbeta;,andbeta;-dihaloenone compounds from diazodicarbonyl compounds. According to the present invention, a diazo compound reacts with an oxalyl halide in the presence of a ruthenium catalyst so andalpha;,andbeta;- and andbeta;,andbeta;-dihaloenones can be synthesized through one-step reaction in an easy, simple and environmental manner. The synthesized andalpha;,andbeta;- and andbeta;,andbeta;-dihaloenones can be widely used for synthesis of intermediates of various drugs, natural materials, agricultural pesticides, dyes, etc. due to various biological activities.COPYRIGHT KIPO 2017
