“…The next step was the hydrolysis of the bromide to benzyl alcohol, which underwent intramolecular esterification [8,33,34] The method can be modified by using corresponding benzyl iodide instead of bromide [21] (A1a). 3-Methyl-substituted benzoxaboroles were obtained similarly by using 2-ethylphenylboronic acid [35] (A1b).…”

“…The crystal structures were obtained by XRD measurements with a Stoe IPDS diffractometer (5) or an Oxford Diffraction Gemini Ultra diffractometer (others). The mass spectra were recorded with a [9] [ 5 CpFeBr(dme)] (dme = 1,2-dimethoxyethane), [10] mesitylmagnesium bromide, [16] mesityl(tri-tert-butylcyclopentadienyl)iron (1), [6] (2,6-diisopropylphenyl)magnesium bromide, [10] (2,6-diisopropylphenyl)(tetraisopropylcyclopentadienyl)iron (3), [8] and (2,6-diisopropylphenyl)-(pentaisopropylcyclopentadienyl)iron (4) [10] were synthesized according to literature procedures. Hexachloroethane (Acros, 99 %) was used as purchased.…”

“…Dagegen kommt es bei sperrigen Substituenten bevorzugt zur Bildung von Cyclodimeren. [8][9][10] Es gibt jedoch nur wenige Beispiele für solche 1,3,2,4-Dioxodiboretane, und nach unserem Wissen konnte bis jetzt nur ein Derivat verlässlich über Röntgendiffraktometrie charakterisiert werden (2). [11] Weiterhin wurde auf monomere Oxoborane mit großen Substituenten als reaktive Zwischenstufen aus verschiedenen Abfangversuchen geschlossen, [10,12] die sich über intramolekulare Prozesse (z.…”
