    Hydroboration of 1,1'-Bi(cyclopent-1-ene) and 3,3'-Biindene: Experimental and Theoretical Study.

  • Original language description

    Hydroboration of bi(cyclopent-1-ene) and 3,3'-biindene with borane, thexylborane or (?)-isopinocampheylborane afforded, regardless of reaction conditions, meso-isomers of the corresponding diols as the main products. No reaction was observed with 9-BBN.The structure of both major and minor isomer of 1,1'-biindane-2,2'-diol was assigned on the basis of 1H NMR spectra of the corresponding Mosher?s diesters. The stereochemistry of the meso-isomer of 1,1'-biindane-2,2'-diol was confirmed by a single-crystal X-ray analysis of the corresponding dimesylate. To explain the observed stereoselectivity, a theoretical study of the complexes of monohydroborated intermediate with borane was made using DFT methods.

    Hydroborace 1,1'-bi(cyklopent-1-en)u a 3,3'-biindenu: experimentální a teoretická studie.

  • Czech description

    Hydroborace bi(cyklopent-1-en)u a 3,3'-biindenu boranem, thexylboranem nebo (?)-isopinocampheylboranem poskytla bez ohledu na reakční podmínky meso-izomery odpovídajících diolů jako hlavní produkt. V případě 9-BBN nebyla pozorována žádná reakce. Struktura jak majoritního, tak minoritního izomeru 1,1'-biindan-2,2'-diolu byla určena na základě 1H NMR spekter odpovídajících Mosherových diesterů. Stereochemie meso-izomeru 1,1'-biindan-2,2'-diolu byla potvrzena rentgenovou strukturní analýzou odpovídajícíhodimesylátu. Pro objasnění pozorované stereoselektivity byla provedena teoretická studie komplexů monohydroborovaných intermediátů s boranem metodami DFT.
