Chiral Heterocyclic Ligands. X. Synthesis and Metal Complexes of Hindered and Chiral 2,2′-Bipyrimidines
2004
Australian journal of chemistry (Print)
The first examples of 2,2'-bipyrimidine ligands incorporating bulky or chiral substituents have been prepared by nickel(0)-mediated homo-coupling reactions of chloropyrimidines. The 4,4'-di-(tert-butyl) derivative 2 and the chiral derivative 5, with 4,5-fused bornane groups, have been shown to form mononuclear metal complexes in which they coordinate through the less hindered nitrogen donors.
