Ionic liquids as a reusable media for copper catalysis. Green access to alkenes using catalytic olefination reaction

It was demonstrated that ionic liquids are superb recyclable media for copper catalyzed reactions using catalytic olefination reaction as an example. As a result a novel green access to the halogenoalkenes was elaborated. Possibility to perform up to five reaction cycles without catalyst leaching and decreasing of the yield was demonstrated. A number of various ionic liquids was screened and 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim] [BF4]) was found the solvent with highest efficiency. Mild conditions, high atom economy comparing to other known methods, low amounts of wastes and possibility to recover ionic liquid are the advantages of the proposed method.

Novel ambiphilic dichlorocarbenoid equivalent in alkene cyclopropanation and carbonyl olefination

The Ti-Mg-dichloromethylene complexes derived from the oxidative addition of CCl4 to the Mg-TiCl4 bimetallic species serve as a novel class of ambiphilic dichlorocarbenoid equivalents. Not only is Ti-Mg-dichlorocarbenoid highly selective but also it seems highly reactive in both alkene cyclopropanations and carbonyl dichloromethylenations.

A novel approach to the synthesis of 2-aryl propionates

A two step conversion of phenyl glyoxylates to 2-aryl-propionates has been accomplished. Esters of phenylglyoxylic acid have been converted to corresponding β,β-dichlorostyrenes. These on further reduction gave esters of 2-arylpropionic acids.

Ramberg-Backlund rearrangement vs. β-Elimination of haloform from trichloro and trifluoromethyl sulfones

A new and convenient method for the preparation of trichloro and trifluoromethanesulfinates is described. These esters readily undergo rearrangement to the corresponding sulfones at room temperature, in high yields. In contrast to trichloromethyl sulfoxides which undergo base-induced β-elimination of chloroform to sulfines, the corresponding sulfones undergo an unusually facile Ramberg-Backlund rearrangement with formation of dichloromethylene products. Replacement of CCl3 by CF3 results in complete loss of reactivity, even under drastic basic conditions.

A facile method for the preparation of 1,1-dichloroolefins using benzenesulfonyl chloride as a chlorenium ion source

Reaction of the lithio anion derived from diethyl methylphosphonate with benzenesulfonyl chloride gives directly the (diethylphosphoryl)dichloromethyllithium. In situ reaction with aldehydes or ketones gives in high yields of 1,1-dichloroolefins in a convenient one-pot procedure.

Energy Barrier for 1,2-Chlorine Migration in α-Methyl-α-chlorobenzyl(chloro)carbene

An activation energy of 3.4 kcal mol-1 (1 cal = 4.184 J) was obtained for the 1,2-chlorine migration in α-methyl-α-chlorobenzyl(chloro)carbene.

Monophenylation accompanied by partial reduction of 1,1-dihalogeno-2-phenyl-1-alkenes in the presence of a nickel-phosphine complex

Reaction of 1,1-dihalogeno-2-phenyl-1-alkenes (I) with phenylmagnesium bromide in the presence of NiCl2(dppp) in THF has been studied.Mono-cross-coupling accompanied by partial reduction gave (E)-1,2-diphenyl-1-alkenes (III) as the major products.Use of a large excess of Grignard reagent increased the yields of III and the (Z)-isomers (II), with a decrease in the yield of double cross-coupling products, 1,1,2-triphenyl-1-alkenes (IV).The highest ratio of the sum of the yields of the monophenylation products to the yield of the double cross-coupling product, (II+III)/IV=36.5, was found for the reaction of PhMgBr with 1,1-dibromo-2-phenylpropene (Ib) in a 12.0/1 molar ratio.A possible reaction mechanism is described.
