Oxygen initiated unprecedented condensation of propargylamine into the 1,3-di(propargylimino)propylateanion coordinated to cobalt(iii)
Abstract
Condensation of coordinated propargylamine into the
unprecedented 1,3-di(propargylimino)propylateanion, an analogue of the
acetylacetonate anion, is initiated by dioxygen in the Co(II)
polymeric trimethylacetate complex/NH2CH2CCH
system; molecular structures of the intermediate complex,
Co(O2CCMe3)2(H2NCH2
C
CH)4 and final product
Co(O2CCMe3)2(NH2CH2
C
CH)2[N,N′-(HC
CCH
2NCHCHCHNCH2C
CH)] were established by X-ray
analysis.
