The reaction of 5-amino-4-chloroquinolines with 4-amino-2,6-di-tert-butylphenol yielded derivatives of spiro[6-azaperimidine-2,4'-cyclohexa-2',5'-dien]-1'-one, which exhibit photo-and thermochromic properties in solutions. The structure of 2',6'-di-tert-butyl-5,7,9-trimethylspiro[6-aza-2,3-dihydroperimidine-2,4'-cyclohexa-2',5'-dien]-1'-one was established by X-ray diffraction study. The ring-chain isomerization of 2',6'-di-tert-butyl-5,7-dimethyl- and 2',6'-di-tert-butyl-5,7,8-trimethylspiro[6-aza-2,3-dihydroperimidine-2,4'- cyclohexa-2',5 -dien]-1'-ones was studied by dynamic NMR spectroscopy.
