Deoxygenation of Some α-Dicarbonyl Compounds by Tris(diethylamino)phosphine in the Presence of Fullerene C60
摘要:
The reactions of such cyclic alpha-diketones as acenaphthenequinone, aceanthrenequinone, and N-alkylisatins, with hexaethyltriaminophosphine in the presence of the fullerene C-60, lead to the formation of methanofullerene derivatives under mild conditions. This process proceeds via deoxygenation of the dicarbonyl compound by the P(III) derivative and is likely to involve the intermediate formation of alpha-ketocarbenes. The structure of some methanofullerenes has been confirmed by NMR and XRD. The electrochemical behavior of the methanofullerenes was also investigated.

The three-component reaction of acenaphthenequinone, fullerene C 60 and hexaethyltriaminophosphine leads to the formation of the new methanofullerene – 2-3’-cyclopropa[1,9](C 60 -I h )[5,6]fulleren-3’-yl}-1-acenaphthenone.
