  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 chlorohydrins bearing chloro- and hydroxyl groups in the cis-conformation. Chemoselective carbonyl addition to acyclic α-halo ketones was followed by effective cyclization to 2-(2-oxoethyl)oxiranes. The structural and bonding

  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.

  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 Sn-119 NMR spectrum and increased coupling constants J(Sn-119-C-13), compared with the four-coordinate tin enolate 1(e). The tautomeric equilibrium between C-stannyl ketone 1(k) and O-stannyl enolate 1(e) was changed by the addition of HMPA, the percentage of enol form being increased. The resulting five-coordinate tin enolates 1(h) showed high reactivity and selectivity for halide displacement in reactions with alpha-halo ketones 2. The tin enolates, when coordinated by Bu(4)NBr, effected a selective reaction with alpha-halo imines 5 to give a variety of gamma-imino ketones 6, which were subsequently hydrolyzed to 1,4-diketones or cyclodehydrated to substituted pyrroles 9.
