One-Step DMT Synthesis
[ Back to the Chemistry Archive ]
Cyclisation reaction involving nitro- and nitroso- groups with tervalent phosphorus compounds.
Reaction with 2-(2-nitrophenyl)-4-dimethylamine butene:
(2-NO2)C6H4-C(CH2CH2N(CH3)2)=CH2 DMT 58 %
Reaction with 2-Nitrostyrene:
A good starting compound for 2-(2-nitrophenyl)-4-dimethylamine butene would be 2-nitrocinnamic aldehyde.
