INTERMEDIATES IN THE REACTIONS OF CHLORANIL AND 2,6-DICHLORO-1,4-BENZOQUINONE WITH PYRROLIDINE

Although the intermediates in the reactions of chloranil and 2,6-dichl oro-1,4-benzoquinone with pyrrolidine are the corresponding monoaminat ed chloroquinones, these compounds exhibit a pronounced tendency to fo rm molecular complexes; thus, the spectral characteristics of 2,3,5-tr ichloro-6-pyrrolidino-1,4-benzoquinone indicate its partial self-compl exation into the corresponding biradical dimer. 2,6-Dichloro-3-pyrroli dino-1,4-benzoquinone forms a stable quinhydrone complex with 2,6-dich lorohydroquinone.
