(Z)-Alkyl α-Cl-α,β-unsaturated esters are prepared in excellent yields by stereoselective dehydrobromination of alkyl α-Br-α-Cl-carboxylates with LiClLi2CO3 in dimethylformamide.
(Z)-烷基α-Cl-α,β-不饱和酯是通过在二甲基甲酰胺中用LiCl 3 Li 2 CO 3对烷基α-Br-α-Cl-羧酸酯进行立体选择性脱氢溴化而制得的。
The Mukaiyama reaction of ketene bis(trimethylsilyl) acetals with α-halo acetals

日期:——
Ketene bis(trimethylsilyl) acetals were reacted with α-halo acetals giving β-alkoxy-γ-halo acids which were converted to butenolides by reaction with two equivalents of base. This constitutes a novel and short butenolide synthesis.
The present invention relates to the compounds of formula (I), and the N-oxides, stereoisomers, tautomers and agriculturally or veterinarily acceptable salts thereof wherein the variables are defined according to the description. The compounds of formula (I), as well as the N-oxides, stereoisomers, tautomers and agriculturally or veterinarily acceptable salts thereof, are useful for combating or controlling invertebrate pests, in particular arthropod pests and nematodes. The invention also relates to a method for controlling invertebrate pests by using these compounds and to plant propagation material and to an agricultural and a veterinary composition comprising said compounds.
