Nokami, Toshiki published the artcileElectrochemical synthesis of dendritic diarylcarbenium ion pools, Quality Control of 457-68-1, the publication is Tetrahedron (2011), 67(25), 4664-4671, database is CAplus.
Dendritic diarylcarbenium ion pools were synthesized by the low temperature electrochem. oxidation of the corresponding dendritic (diarylmethyl)trimethylsilanes, which were prepared by use of the iterative method consisting of electrochem. activation and Friedel-Crafts type coupling. Time-course NMR studies revealed that thermal stability of dendritic diarylcarbenium ions depends both on the generation of the dendritic structure and on the para-substituents of the terminal Ph groups. Dendritic diarylcarbenium ions up to the third generation exhibited high reactivity as a carbon electrophile.
