• Conversion of some dihalogenocyclopropanes into unsaturated ketones

  日期：——

  Dibromocyclopropanes, prepared by addition of dibromocarbene to cyclic olefins, give unsaturated ketones, with ring expansion, when treated with silver sulphate in concentrated sulphuric acid at room temperature. Mild hydrogenation of a dibromocyclopropane gave equivalent amounts of the monobromocyclopropane and of a ring-opened bromine-free compound.

  A method for producing an &agr;,&agr;-difluorocycloalkane at high purity with good efficiency, which comprises a step of treating a fluorocycloalkene with hydrogen fluoride wherein the fluorocycloalkene has one fluorine atom directly bonded to a carbon atom of carbon-carbon unsaturated double bond, more preferably, a step of directly adding the hydrogen fluoride to a reaction mixture obtained by treating the cycloalkanone with the de-oxygen fluorinating agent.

• Generation of Cycloheptyne during the Solvolysis of Cyclohexylidenemethyliodonium Salt in the Presence of Base

  DOI：10.1246/bcsj.76.1849

  日期：2003.9

  Solvolysis of 4-methylcyclohexylidenemethyl(phenyl)iodonium tetrafluoroborate (1) and its R isomer (69% ee) was carried out in 2,2,2-trifluoroethanol (TFE) and 1,1,1,3,3,3-hexafluoropropan-2-ol (HFP) in the presence of bases such as acetate, pyridine, triethylamine, and alkoxide. The reaction is much faster in TFE than in HFP. Products in TFE include solely un-rearranged (racemized) enol ether 2 together with iodobenzene, while the main product in HFP is ring-expanded (partially racemized) 1-alkoxycycloheptene 3. Results show that 2 is formed via α-elimination with alkylidenecarbene as an intermediate, while the reaction in HFP to give 3 involves a cycloheptyne intermediate that is mostly derived from an intermediate cyclohept-1-enyl cation via the E1-type pathway.

  4-甲基环己烯基甲基（苯）碘铵四氟硼酸盐（1）及其R异构体（69% ee）的溶剂解反应在存在醋酸盐、吡啶、triethylamine和烷氧基化合物的情况下，在2,2,2-三氟乙醇（TFE）和1,1,1,3,3,3-六氟丙烷-2-醇（HFP）中进行。在TFE中的反应速度远快于在HFP中的反应。TFE中的产物仅包括未重排的（消旋化的）烯醇醚2以及碘苯，而HFP中的主要产物是扩环的（部分消旋化的）1-烷氧基环庚烯3。结果表明，2是通过α-消除反应形成的，烷基烯基碳烯作为中间体，而在HFP中生成3的反应涉及一个主要来源于中间体环庚-1-烯阳离子的环庚炔中间体，通过E1型路径实现。
