摘要：

The complex formation between three tris(oxaalkyl) berates (B2, B3, B4) and SbCl5 as well as the structure of these complexes were studied by calorimetric and NMR methods. Results of the calorimetric titration indicate a dependence of Delta H of the reaction heats on the length of the oxaalkyl chains, and a formation of stable complexes. The H-1 and C-13 NMR data confirmed the formation of the respective stable complexes. The structure of the complexes is discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
