Ethanolamine → 2,2'-[(2-Nitroethene-1,1-diyl)diazanediyl]di(ethan-1-ol)

Participants

Reaction Steps

78 ml of 2-aminoethanol (1.3 moles) were added slowly over half an hour to a solution of 95 g of 1,1-bis(methylthio)-2-nitroethene (0.57 mole) in 500 ml of toluene at 80° C. After the addition, the mixture was held at 80° C. for half an hour, was cooled to room temperature and the solid formed was filtered off, washed with chloroform (2×100 ml portions) and was dried to give 107 g N,N'-bis(2-hydroxyethyl)-2-nitro-1,1-ethenediamine (97-98% yield) in yellowish crystal form. m.p. 145°-146° C.
