We have studied the reactions of salts of nitroalkanes with tropylium and 2,6-diphenylpyrylium salts leading to products of C-tropylation and C-pyrylation of the corresponding anions. The only exception is the salt of cyanodinitromethane, which is not tropylated. Splitting off of a HNO2 molecule from the products of tropylation of nitroalkane anions to prepare nitroheptafulvenes was unsuccessful.
