Abstract: | Perfluoromethyl-Element-Ligands. XVII. Formation of Adducts of MenE(CF3)3?n Ligands with BX3 Compounds (Me = CH3; E = P, As, Sb; n = 0–3; X = H, CH3, Hal) The ligands MenE(CF3)3?n (Me = CH3; E = P, As, Sb; n = 0–3) have been prepared (partly using new methods) and studied by n.m.r. spectroscopy (1H, 19F, 31P, 13C). In order to deduce their relative donor strength their reactions with the Lewis acids “BH3”, BMe3, BMe3, Me2BBr, and BX3 (X = F, Cl, Br) have been studied. Control of adduct formation occurs by n.m.r. spectroscopy (1H, 19F). The following series of decreasing basicity or acidity are obtained: |
