Abstract

The synthesis and characterisation (TP, multielement NMR spectroscopy) of B(C6F5)(3). L {L = CH3CO . OEt (1), Et3PO (2)} are described together with a single-crystal X-ray diffraction study of 2. The latter reveals an angular B-O-P linkage {161.04(16)degrees} with BO and PO bondlengths of 1.533(3) and 1.4973(17) Angstrom, respectively. Lappert's ?v(CO) and Gutmann's acceptor number (AN) methods have been applied to 1 and 2 to assess the relative Lewis acidity of B(C6F5)(3) which is confirmed as weaker than BF3. A strong linear correlation has been obtained for Gutmann's AN and Childs' H-1 NMR Lewis acidity scales.
