Аннотация: For the first time, a correct ²⁷Al chemical shift and W_1/2 for 134 ppm Al(C₆F₅)₃ as the most widely used Al-based ‘super-electrophilic’ Lewis acid was determined. A step-by-step proper way for acquisition and processing challenging ²⁷Al spectra is suggested, which is applicable for any organo-aluminium compounds with asymmetric environment of Al. Using this procedure, several Lewis pairs of Al(C₆F₅)₃ with N,O,S,P-centered Lewis bases were characterized.

Ключевые слова: tris(pentafluorophenyl)aluminium, super-electrophilic Lewis acids, ²⁷Al NMR, organoaluminium compounds, frustrated Lewis pairs.
