Fluorodenitration of activated diphenyl sulphones using tetramethylammonium fluoride
摘要:
Fluorodenitration of nitro-substituted diphenyl sulphones occurs readily in dipolar aprotic solvents using tetramethylammonium fluoride as the source of fluoride, although other reactions including fluorodesulphonylation can sometimes occur in competition.
Isomerisation accompanying fluorodenitration of trifluoromethyl activated diphenyl sulfones
摘要:
Fluorodenitration of 2-(4-chlorobenzene sulfonyl)-5-nitrobenzotrifluoride using tetramethyl ammonium fluoride affords a mixture of 2-fluoro-5-nitrobenzotrifluoride and two isomers of (4-chlorobenzene sulfonyl)-fluorobenzotrifluoride
