    三卤代环丙烷与甲基锂反应制得的1-卤代环丙烯和炔丙基卤化物
    摘要:
    1,1,2-三卤代环丙烷(卤素=氯或溴)在与甲基锂反应时会进行1,2-脱卤作用,在许多情况下,产物是1-卤代环丙烯。在(20,X = Br,Cl)和(25)的反应中,即使在低温下也会发生重排,并分离出炔丙基卤,而(16)转化为2-氯环己-2-烯基,可能被呋喃捕获。

    Formation of Acetylenic Acetals by Ring Opening of 1,1,2-Trihalocyclopropanes under Phase-Transfer Conditions.
    摘要:
    A number of substituted 1,1-dibromo- and 1,1-dichlorocyclopropanes with an additional chlorine or bromine atom attached to C-2 were synthesized in reasonable to good yields by dihalocarbene addition to the corresponding alkenes under phase-transfer conditions. When the trihalides were treated with 50% aqueous sodium hydroxide in the presence of ethanol, triethylbenzylammonium chloride and dichloromethane, most of the compounds underwent ring opening and afforded mixtures of acetylenic acetals, usually in good yields. The reaction most likely involves cyclopropene intermediates, which in some cases also rearrange to a minor extent to the corresponding vinylcarbenes and afford alpha,beta-unsaturated aldehydes.

  • SYNTHESIS OF β, γ-UNSATURATE CARBOXYLIC ACID DERIVATIVES BY THE NOVEL Ni (CO)<sub>4</sub>-INDUCED RING-OPENING CARBONYLATION REACTION OF 1,1-DIBROMO-2-CHLOROCYCLOPROPANES

    1,1-Dibromo-2-chlorocyclopropanes underwent the Ni (CO)4-induced ring-opening carbonylation reaction with alcohol or amine giving the β, γ,-unsaturated carboxylic acid and dicarboxylic acid derivatives. Use of N,N-dimethyltrimethylsilylamine as an initial nucleophile in the presence of benzaldehyde led to a dienecarboxamide presumably via codensation of the nickel enolate intermediate.

    surfaces for the potential pyrolysis pathways. Although the potential cyclopropylidene species in these rearrangements are significantly stabilized, for none of the systems was this sufficient to permit isomerization via these intermediates. 36b is calculated to rearrange via a vinylidene intermediate to give 3-methyl-1-trimethylsilyl-1-butyne (47), in agreement with experiment.
