参考标题:Specific Ortho Orientation In The Vicarious Substitution Of Hydrogen In Aromatic Nitro Compounds With Carbanion Of Chloromethyl Phenyl Sulfone 作者:M. Makosza,T. Glinka,A. Kinowski |发布日期:1984.1 摘要:Vicarious Nucleophilic Substitution Of Hydrogen Atoms In Nitroarenes With Chloromethylphenyl Sulfone Proceeds Selectively Ortho To The Nitro Group When Carried Out In T-Buok/thf Base/solvent System. In The Majority Of 3-Substituted Nitrobenzene Derivatives Substitution Occurs At The Most Hindered Position 2. These Conditions Offer An Efficient Method Of Synthesis Of 2,6 And 2,3-Disubstituted Nitrobenzene
