WebThe Chugaev elimination is a chemical reaction that involves the elimination of water from primary alcohols to produce terminal alkenes.The intermediate is a xanthate. It is named … WebXanthates, Chugaev elimination The Chugaev elimination is of synthetic value, because it proceeds without rearrangement of the carbon skeleton.Other non-thermolytic elimination procedures often lead to rearranged products, when applied to the same substrates. However applicability of the Chugaev reaction is limited if the elimination is possible in …
WebThe Cope reaction or Cope elimination, developed by Arthur C. Cope, is an elimination reaction of the N-oxide to form an alkene and a hydroxylamine. Mechanism and applications. The reaction mechanism involves an intramolecular 5-membered cyclic transition state, leading to a syn elimination product, an E i pathway. This ... WebMar 15, 2011 · In this chapter the Chugaev reaction is defined as the thermal decomposition of the xanthate ester of an alcohol that contains at least one beta-hydrogen atom to produce one or more olefins, carbon oxysulfide and a mercaptan. The formation of olefins by the pyrolysis of xanthates was discovered in 1899 by Chugaev in connection …

Only the end group is lost at ~180°C and the dominant mechanism is proposed to be a concerted elimination process analogous to that involved in the Chugaev reaction. 展开
Chugaev discovered that dimethylglyoxime forms a scarlet solid upon reaction with nickel(II) ions. This reaction was one of the first "spot tests" for a metal ion. An adherent to the theories of Alfred Werner, Chugaev made several contributions to the chemistry of platinum. The salt [Pt(NH3)5Cl]Cl3 containing the chloropentammineplatinum(IV) ion, is called "Chugaev's salt". Other complexes prepared in his laboratory include [Pt(SEt2)4][PtCl4], [Pt(NH3)5OH]Cl3, [Os(S…
WebIn organic chemistry, the oxy-Cope rearrangement is a chemical reaction.It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]-sigmatropic rearrangement..
