A Ditetrylyne as a π-Electron Donor: Synthesis and Characterization of [AgAr′GeGeAr′]+SbF6− and [Ag2Ar′GeGe(F)Ar′]+SbF6− (Ar′ = C6H3-2,6(C6H3-2,6-Pri2)2)
摘要:
The reaction of a digermyne Ar'GeGeAr' (Ar' = C6H3-2,6-(C6H3-2,6-Pr-2(i))(2)) with AgSbF6 at -40 degrees C forms the complex (AgAr'GeGeAr')+SbF6-, which provides the first example of a heavier group 14 element alkyne analogue behaving as a pi donor to a transition metal. The cation (AgAr'GeGeAr')(+) is best described as a hybrid of a pi-complex and a sigma-metallacyclopropene structure.
