An improved method for the preparation of cyclic conjugated nitroolefins

Ghosh, Debasis,Nichols, David E.

, p. 195 - 197 (1996)

Nitration of cyclic conjugated olefins was achieved in a one-pot procedure using nitryl iodide generated in situ from iodine and potassium nitrite complexed with 18-crown-6 in tetrahydrofuran under sonication/stirring, followed by treatment of the unstable iodo nitro compound with base. The yield of the nitro compound varied from 52 to 90%.
