On the Mechanism of the Vicarious Nucleophilic Substitution of Hydrogen in Nitroarenes
Makosza, Mieczyslaw,Glinka, Tomasz
, p. 3860 - 3861 (1983)
On the basis of the isotope effect and the effect of base on the reaction rate the main features of the mechanism of the vicarious nucleophilic substitution of hydrogen were established.The reaction proceeds via fast and reversible addition of the carbanions to the nitroarenes followed by slower base-induced β-elimination.
Simple Synthesis of Aryl p-Nitroarylacetonitriles by Vicarious Nucleophilic Substitution with Carbanions of Protected Cyanohydrins
Rad, Nazar,M?kosza, Mieczys?aw
, p. 376 - 380 (2018/01/27)
Acetals of the cyanohydrins of aromatic aldehydes were deprotonated to generate carbanions, which were used in the vicarious nucleophilic substitution of the hydrogen atom of aromatic and heteroaromatic nitro compounds to form p-nitro-substituted diarylac
Oxidative nucleophilic substitution of hydrogen in nitroarenes with phenylacetonitrile derivatives
Makosza, Mieczyslaw,Stalinski, Krzysztof
, p. 8797 - 8810 (2007/10/03)
Tertiary carbanions generated from α-substituted phenylacetonitriles in liquid ammonia add to nitrobenzenes in the para position to form the corresponding σ(H)-adducts which are transformed, depending on the starting nitriles and the reaction conditions, to products of oxidative nucleophilic substitution of hydrogen, ONSH or vicarious nucleophilic substitution, VNS.
