The Ferrier carbocyclization (or Ferrier II reaction) is an organic reaction that was first reported by the carbohydrate chemist Robert J. Ferrier in 1979. [1] [2] It is a metal-mediated rearrangement of enol ether pyrans to cyclohexanones. Typically, this reaction is catalyzed by mercury salts, specifically mercury(II) chloride.
The Ferrier rearrangement is an organic reaction that involves a nucleophilic substitution reaction combined with an allylic shift in a glycal (a 2,3-unsaturated glycoside). It was discovered by the carbohydrate chemist Robert J. Ferrier. [1] [2] A typical Ferrier rearrangement

[4] [5] The reaction has since been extended to the synthesis of β-keto esters from the condensation between aldehydes and diazo esters. [6] The general reaction scheme is as follows: General Scheme for Buchner Reaction. The reaction yields two possible carbonyl compounds (I and II) along with an epoxide (III). The ratio of the products is ...
Product mixtures of Buchner reactions resulting from thermal Rhodium II-catalysts are less complicated. Wyatt et al. have studied the regioselectivity of the thermal Buchner reaction using Rh 2 (O 2 CCF 3) 4 and demonstrated that the electrophilic character of the rhodium carbene prefers reaction at the more nucleophilic π-bonds of the ...
The first reactions to the year’s most-anticipated sequel have rolled in after its first ever screening. On Friday (18 October), Gladiator 2 premiered in Los Angeles at a screening introduced by ...
The reaction has a wide scope, as shown in Figure 16, owing to the high Lewis acidity of the catalysts, which can activate even weakly nucleophilic olefins, such as 1-hexene and cyclohexene. Figure 15. C2-symmetric Cu(II) catalysts developed for the enantioselective carbonyl-ene reactions of olefins and ethyl glyoxylate Figure 16. Scope of the ...
