Sv. Rubashko et al., THE THERMAL-STABILITY OF 2-ARYLAMINO AND 2-ALKYLAMINO-3-CYCLOALKYLAMIN-1,4-NAPHTHOQUINONES, Sibirskij himiceskij zurnal, (2), 1993, pp. 65-72
The thermal stability are affected by structure of cycloalkylaminogrou
p and are not affected by substituents in aromatic ring. The heating o
f compounds (I - XII) to decomposition point leads to the formation of
2-arylamino-1,4-naphthoquinones and the fragmentation of cycloalkylam
ine.
