Abstract
Disclosed is a process for producing .beta.-nitroenamine represented by the formula I: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and independently indicate a hydrogen atom or a C.sub.1 -C.sub.10 alkyl group which may be optionally substituted with at least one group selected from the group consisting of a halogen atom, a lower alkoxy group, an aryloxy group, a hydroxyl group or an aryl group, or an aryl group which may be optionally substituted with a halogen atom, a lower alkyl group, a lower alkoxy group, an aryl group, an aryloxy group, a nitro group, a cyano group, an acylamino group, a di-lower alkylamino group, an arylamino group, a hydroxyl group, an arylsulfonyl group, a mercapto group, a lower alkylthio group or an arylthio group, R.sub.1 and R.sub.2 may bond together to form a cycloalkyl or bicycloalkyl and R.sub.3 is a hydrogen atom, a lower alkyl group, a cycloalkyl group or an aralkyl group; and an intermediate for producing the .beta.-nitroenamine.
