salts of primary and secondary nitrocompounds (nitroethane, 1- and 2-nitropropanes, nitrocyclohexane, and nitrocycloheptane) in the presence of excess halide, nitrite, cyanide, and phenylsulfinate anions under undivided and divided amperostatic electrolysis conditions in a two-phase medium (CH2Cl2/H2O) produces geminal nitrohalides (35–85% yields), dinitro compounds (15–51%), nitronitriles (6–27%)

Visible light induced ringexpansion of N-tosylaziridines with 1-bromo-1-nitroalkanes to afford 2-nitroazetdines in moderate to excellent yields with high regio- and diastereoselectivity is reported. The salient features of the protocol include the first synthesis of 2-nitroazetidines, operational simplicity, utilization of clean, inexpensive and sustainable resources like visible light and atmospheric

日期:——
An organocatalytic asymmetric synthesis of spironitrocyclopropanes has been demonstrated starting from 2-arylidene-1,3-indandiones and bromonitroalkanes catalyzed by a cinchona-derived bifunctional organocatalyst. The products were obtained with excellent enantioselectivities, diastereoselectivities and with good yields.

α-Nitroalkyl radicals generated from gem-halo nitro compounds are reactive enough to undergo the carbon–carbon bond forming reaction with allyltributylstannane via radical chain processes, which provides a new method for the introduction of an allyl group into nitroalkanes.

group attached to the C-3 atom of five- and six-memberedcyclic nitronates (isoxazoline N-oxides and oxazine N-oxides, respectively) has been studied. The process involves silylation of starting 3-methyl-substituted cyclic nitronates followed by halogenation of the resulting N-(silyloxy)enamines. While five- and six-memberedcyclic enamines behave similarly toward elemental bromine and iodine, their
