The Synthesis and Complex Formatirn of Stererisomers of some new α-Dioximes

Abstract
Two new α-dioximes, 1,4-diphenyl-2,3-bis(hydroxyimino)-piperazine, DBPH2, and bis(α-mercaptopyridyl)glyoxime, BMGH2, and their stereoisomers have been isolated. Their complexes with various transition metal ions have been synthesized. The transformation of the amphi-DBPNi(II) complex to anti-form has been investigated. The structures of all isolated compounds were proposed on the basis of analyses, i.r. and u.v-visible data.
