Kosal, Andrew D.; Ashfeld, Brandon L. published an article in Organic Letters. The title of the article was 《Titanocene-catalyzed conjugate reduction of α,β-unsaturated carbonyl derivatives》.Electric Literature of C11H13ClO2 The author mentioned the following in the article:
A titanocene-catalyzed conjugate reduction of α,β-unsaturated carbonyl derivatives has been developed. A series of carbonyl compounds including aldehydes, ketones, esters, and amides proved viable in the reduction process providing an efficient, chemoselective method for the catalytic reduction of unsaturated carbonyl derivatives After reading the article, we found that the author used Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Electric Literature of C11H13ClO2)
Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. Electric Literature of C11H13ClO2 The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.
