TY  - JOUR
AB  - Nmr evidence is obtained for mixtures of geometrical stereoisomers of carbanions in DMSO solution of bis(4-)- and bis(2-pyridyl)methane (1) and (2), bis(2-pyridyl)acetonitrile (3), and bis(2-quinolyl)methane (4). When incorporated into π-charge/shift relationships the 13C and 15N nmr data provide access to charge demands cx of the heterocycles, that is the fraction of π-charge withdrawn by the rings from the carbanionic carbon. Compounds(3)and(4)behave as ligands LH, whose anions L- produce neutral chelates with divalent metal ions (Met = Zn2+, Pd2+). With Met = Co2+, Cu2+, Mn2+ the ligand LH 3 affords the dimer L2. © 1995.
