NOVEL SUPERELECTROPHILIC COMPLEXES FOR LOW-TEMPERATURE ALKANE AND CYCLOALKANE TRANSFORMATIONS

The results of studies on the elaboration of new superelectrophilic co mplexes and their use for efficient low-temperature transformations of alkanes and cycloalkanes, such as cracking, isomerization, alkylation , and single-step functionalization (acylation, carbonylation, ionic m onobromination, sulfurization, thioacylation, etc.), are summarized. T he activity of new aprotic organic and inorganic superacids is compare d to that of known electrophilic systems, including protic superacids. The reasons for the superelectrophilic properties of new active syste ms are considered.
