Article abstract of DOI:10.1039/DT9940003507

Dimeric Li reacted with the nitriles 4-XC6H4CN (X = H or Me) in diethyl ether-hexane (1:10) to yield dimeric complexes <4-XC6H4C(NSiMe3)2*Li(NCC6H4X-4)>2 (X = H 1 or Me 2).Complex 2 is dimeric in the solid state with two four-co-ordinated lithium cations bound in N,N'-bidentate ? fashion to one amidine anion (chelating), forming a double diazaallyl lithium bridge, in a monodentate ? fashion to a nitrogen lone pair of a substrate molecule, and monodentrate to a nitrogen lone pair of a second amidine anion.In solution, rapid interconversion of the different lithium-amidine bonds (? to ? and vice versa) was observed by means of the NMR chemical shifts.
