Halogenated carbonyl ylides in the reactions of mercurial dihalocarbene precursors with substituted benzaldehydes was written by Martin, Charles W.;Lund, Paul R.;Rapp, Erich;Landgrebe, John A.. And the article was included in Journal of Organic Chemistry in 1978.Computed Properties of C9H9ClO2 This article mentions the following:
The reactions of PhHgCBrCl2 (I) with RC6H4CHO [R = H (II), 3-CF3 (III), 4-MeO (IV)] and 2,4,6-Me3C6H2CHO were studied. Relative reactivities with respect to I were III (0.08), II (0.3), BuCH:CH2 (0.3), IV (0.9), cyclohexene (1.0), and Me2C:CMe2 (15.0). Complexation between I and the aldehyde enhanced the rate of decomposition of I to produce :CCl2 of the same reactivity as that from I alone. The intermediacy of dichlorocarbonyl ylides was proposed. In the experiment, the researchers used many compounds, for example, Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6Computed Properties of C9H9ClO2).
Methyl 2-chloro-2-phenylacetate (cas: 7476-66-6) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. 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.Computed Properties of C9H9ClO2
