Two systems for arene sulfenylation were investigated: arenesulfenamides in the presence of SO3 and sulfenylacetate complexes with AlBr3. A preference for the second reagent was demonstrated for sulfenylation of substrates bearing donor substituitents.Translated fromIzvestiya Akademii Nauk.

For the first time, we describe the diene synthesis of 5-chloro-1-alkyl-2-pyridones with N-phenylmaleic imide and have shown that the reaction proceeds nonstereoselectively with formation of a mixture of [4+2]cycloadducts with anendo andexo configuration. We have obtained 1,4-cycloadducts with 4-phenyl-1,2,4-triazoline-3,5-dione.M. V. Lomonosov Moscow State University, Moscow 119899.

A series of previously unreported aldehydes has been prepared by the formylation reaction of dipyrrolo[1,2-a;2':,1'-c]pyrazines and their 5,6-dihydro analogs by DMF and phosphorus oxychloride. 相似文献

Arylselenenation of conjugated and non-conjugated dienes by arylselenenamides in the presence of phosphorus(V) oxyhalides has been studied. Reactions with conjugated dienes lead to 1,4-adducts whilst only addition to double bonds takes place in reactions with non-conjugated dienes. 相似文献

A reaction of monoarylcyclopropanes with nitrosyl chloride activated by sulfur (IV) oxide gave in good yields 5-arylisoxazolines. The reaction is of electrophilic character. A scheme of the reaction was suggested. 相似文献

The molecular and crystal structure of the complex of cupric bromide with 1,5-diphenyl-3,7-dimethyl-3,7-diazabicyclo[3.3.1]nonan-9-ones was studied. The geometry of the complexes of bispydines with cupric halides was shown to depend on the substituent at the nitrogen atom. 相似文献
