Cyclische Carbonsäure‐Organobor‐Verbindungen mit BHB‐Brückenbindung

Abstract: Bei der Reduktion von Glucuronsaure rnit Organo-boranen (R2BH),"] beobachteten wir IR-spektroskopisch die Bildung neuartiger Verbindungen. Es handelt sich dabei um Mischassoziate der nicht reduzierten Sgure mit dem Diorgano-hydro-boran. Solche Assoziate treten auch in Losungen einfacher Monocarbonsauren auf und lassen sich bei geeigneter Substitution der Edukte in kristallisierter Form praparativ gewinnen. I P ? Abb. 2. Projektion des Zelleninhalts von 4. auf die ac-Ebene. 1 und 2 sind kristallographisch unabh… Show more

“…Compounds 2-4 are unique and the structural motif {MOOB} (M = metal) involving trivalent boron is without precedent in main group or transition metal coordination chemistry, although 1,3,4-trioxadiborolanes and alkylperoxyboron entities have been described. [11,19] Note that , but it is not clear whether the Lewis acid is bound to the oxo or to the peroxo ligand. [20] Moreover, only a limited number of transition metal derivatives of boric acid, boronic acid or borinic acid is known.…”
