    Description / Table of Contents: Zusammenfassung 2-Diphenylphosphinato-1,3,2-dioxaborolane und -borinane des Typs (mitG = -CH2CHMe-, -CH2CH2CH2-,-CH2CH2CHMe-, -CMe2CMe2-,-CMe2CH2CHMe-, -CH2CMe2CH2-, -CH2CEt2CH2- und C6H4) erhält man durch Reaktion von Diphenylphosphinsäure mit den entsprechenden 2,2′-Oxo-bis-1,3,2-dioxaborolanen und -borinanen. Die Produkte sind weiße, kristalline, hydrolyseunempfindliche Festkörper. Sie wurden mittels Elementaranalyse, IR-Spektroskopie und multinuklearer NMR-Spektroskopie (11B,31P und119Sn) charakterisiert. Die Resultate legen Strukturen mit monodentaten Phosphinatoeinheiten und dreifach koordinierten Boratomen nahe.
    Notes: Summary 2-Diphenylphosphinato-1,3,2-dioxaborolanes and -borinanes of the type (whereG = -CH2CHMe-, -CH2CH2CH2-, -CH2CH2CHMe-,-CMe2CMe2-, -CMe2CH2CHMe-,-CH2CMe2CH2-, -CH2CEt2CH2-, and -C6H4-) are obtained by the reaction of diphenylphosphinic acid with the corresponding 2,2′-oxo-bis-1,3,2-dioxaborolanes and-borinanes. The products are white crystalline solids, which have sharp melting points and are hydrolytically stable. They have been characterized by elemental analysis, IR and multinuclear NMR (11B,31P, and119Sn) studies. The data suggest structures with monodentate phosphinato moieties and 3-coordinated boron atoms.
