α-IODO-β-NITROSTILBENE IN THE REACTION WITH MORPHOLINE AND PIPERIDINE
Todres, Z. V.,Ermekov, D. S.
, p. 957 - 959 (1992)
The reaction of α-iodo-β-nitrostilbene with morpholine or piperidine yields α-nitro-β-morpholino- or α-nitro-β-piperidinostilbene. The reaction is regioselective and stereospecific: only the iodine, and not the nitro group, is substituted; the product obt

Reaction of cis-α,β-dinitrostilbene (substrate) with morpholine (reagent) in n-hexane leads to cis-α-nitro-β-morpholinostilbene (end product).The process is of first order with respect to the substrate and second order with respect to the reagent.Possible reaction mechanisms are analyzed, and it is established that the following are most probable on the basis of kinetic patterns and stereochemistry: development of a charge transfer complex having a hydrogen bond between the substrate nitro group and reagent amino group; reaction of the complex with a second reagent molecule and formation of a carbanion (this stage determines the overall reaction rate); and detachment of a nitrite ion from the nitrocarbanion and its protonation to form the end product. Keywords: cis-α,β-dinitrostilbene, α-nitro-β-morpholinostilbene, nucleophilic vinylic substitution, hydrogen bond, carbanion, reaction route.

, p. 82 - 86 (2007/10/03)
2-Arylthio- and 2-arylsulfonyl-1-nitro-1-phenylethenes react with amines to give the corresponding nitroenamines whose configuration (E or Z) depends on the amine structure. Primary amines gives rise to Z-nitroenamines, secondary cyclic amines with 2-aryl
Nucleophilic vinyl substitution in 1-Arylthio(sulfonyl)-2-nitroalkenes
Pavlova,Lipina,Kasem,Kuz'mina
, p. 1321 - 1325 (2007/10/03)
Reactions of 1-arylthio-2-nitroalkenes and 1-arylsulfonyl-2-nitroalkenes with N-, O-, and S-nucleophiles result in replacement of the sulfur-containing group. 1-Arylthio-2-nitroalkenes react with arenethiolates with replacement of the nitro group, yielding the corresponding 1,2-bis(arylthio)alkenes.
Stereochemistry in nucleophilic vinylic substitution of activated nitro olefins
Park, Kyong Pae,Ha, Hyun-Joon
, p. 3006 - 3009 (2007/10/02)
Each of E- and Z-isomers of activated α,β-dinitro olefins and α-iodo-β-nitrostilbene reacted ith several different types of nucleophiles such as amines, thiocyanate, and p-toluenethiolate. Only Z-isomers of vinylicsubstituted olefins with amines and thioc
