Catalytic Effect of Five-Coordinate Organotin Bromide or Tetraphenylstibonium Bromide on the Chemo- and Stereoselective Addition of Tin Enolate to α-Halo Ketone

Two types of catalysts, five-coordinate organotin bromides and tetraphenylstibonium bromide, similarly promoted the selective addition of tin enolates to the carbonyl moiety in α-halo ketones.The reaction with 2-chlorocyclohexanones and the enolates gave

SYNTHESIS OF 1,4-DIKETONES, 3,4-EPOXY KETONES, AND 2,4-DISUBSTITUTED FURANS BASED ON THE PRODUCTS FROM CONDENSATION OF THE MAGNESIUM ENOLATES OF KETONES WITH α-BROMO KETONES

4-Bromo-3-hydroxy ketones were obtained by the condensation of methyl ketones with 2-bromo ketones in the presence of tert-butoxymagnesium bromide or by the action of organomagnesium compounds on 2-bromo ketones.The reaction of 4-bromo-3-hydroxy ketones w

NMR Studies of Five-Coordinate Tin Enolate: An Efficient Reagent for Halo Selective Reaction toward α-Halo Ketone or α-Halo Imine

NMR studies of tin enolates 1, in the presence of HMPA, revealed the presence of a five-coordinate O-stannyl enolate 1(h) which contributes to upfield shifts of Sn peaks in the 119Sn NMR spectrum and increased coupling constants J(119Sn-13C), compared wit

Indium-Induced Reaction of Phenacyl Iodide. Deiodinative Dimerization to β,γ-Epoxy Ketone and Aldol Condensation with Aldehydes

The reaction of phenacyl iodide with indium metal gave 3,4-epoxy-1,3-diphenyl-1-butanone which, on treatment with silica gel, gave 2,4-diphenylfuran and 2,4-diphenyl-4-oxobutanal.Metallic indium as well as indium(I) iodide were found to mediate the aldol condensation between α-halo ketone and aldehyde.
