Ec. Constable et al., DIASTEREOSELECTIVE FORMATION OF P-DICOPPER(I) AND M-DICOPPER(I) DOUBLE HELICATES WITH CHIRAL 2,2'-6',2''-TERPYRIDINES, Chemical communications, (5), 1997, pp. 489-490
Chiral 2,2':6',2 ''-terpyridines bearing bornyl groups in the 6-positi
on are prepared; these ligands preferentially form P or M dinuclear do
uble helicates upon coordination to copper(I) which have been structur
ally characterised.
