NITROCYCLOPOPANE IS PREPARED BY REACTING NITROMETHANE AND A 1,2-DIHALOETHANE IN THE PRESENCE OF A BASE AND A POLAR, APROTIC SOLVENT. NITROMETHANE AND 1,2-DIBROMOETHANE REACT IN DIMETHYL SULFOXIDE IN THE PRESENCE OF POTASSIUM CARBONATE WITH THE PRODUCTION OF NITROCYCLOPROPANE.
摘要:
A process for the production of a nitroalkane or dinitroalkane by reacting an olefin or diolefin with nitric acid in the presence of a lower aliphatic monocarboxylic acid anhydride, thereby producing a nitro-ester or dinitro-ester, and reducing the nitro-ester or dinitro-ester with an alkali borohydride to produce the nitroalkane or dinitroalkane.
摘要:
Geminal dinitro compounds are prepared by reacting an organic nitro compound having a replaceable hydrogen on the carbon to which the nitro group is attached with a source of nitrite ions in the presence of an oxidizing agent and a catalytic amount of an alkali metal ferricyanide.
摘要:
Nitrocyclopropane is prepared by reacting 3-chloro-1nitropropane with anhydrous ammonia in the presence of a polar, aprotic solvent. For example, the reaction of 3-chloro-1nitropropane with anhydrous ammonia in the presence of dimethyl sulfoxide produces nitrocyclopropane in high yield.
