For example, tris-pentafluorophenylborane which was found to be the stronger Lewis acid than BF 3 [1] forms stable complexes with electron donors as amines or ethers [2] and it is
WebA series of cyclic esters of pentafluorophenylboronic acid have been obtained and their Lewis acidity evaluated experimentally by a modified Gutmann method. The results based on 31 P NMR measurements were compared with those determined by quantum mechanical calculations at the DFT‐VSXC/pcS‐2 level of theory. The differences in Lewis acidity ...
