Thermal dealkylation of tri-n-octylborane / A. B. Mzinyati in Industrial & engineering chemistry research, Vol. 48 N° 6 (Mars 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 2770–2773 Titre : Thermal dealkylation of tri-n-octylborane : effect of Lewis bases on extent and regioselectivity Type de document : texte imprimé Auteurs : A. B. Mzinyati, Auteur ; D. Jaganyi, Auteur Année de publication : 2009 Article en page(s) : pp. 2770–2773 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Tri-n-octylborane  Dealkylation  Lewis  base Résumé : The dealkylation of tri-n-octylborane in the absence of bulk solvent was investigated in the temperature range 50−200 °C. Results indicate a linear increase in liberation of olefin from the trialkylborane in this temperature range, though the extent of dealkylation is not significant. Investigation of the regioselectivity of the dealkylation reaction shows no thermal-induced back-isomerization on the addition of 10 mol % of Lewis base, though the addition of dimethylformamide, dimethyl sulfoxide, hexamethylphosphoric triamide, and trimethyl phosphate results in back-isomerization of the alkyl chain.
