摘要:
The Lewis acid (C6F5)(3)B was reacted with ICN, NH2CN, C3N3X, (X = H, Cl, F). The resulting Lewis acid base adducts (1-5) were fully characterized by analytic and spectroscopic methods. Additionally, the structures of the adducts 1-4 were determined by single crystal X-ray analyses. It has been qualitatively shown, that a high field shift of the B-11 as well as the F-19 NMR resonances of the o-F atoms of the C6F5-substituents suggests a longer B-N distance.
