M. Schmittel et H. Ammon, A SHORT SYNTHETIC ROUTE TO NOVEL, HIGHLY SOLUBLE 3,8-DIALKYL-4,7-DIBROMO-1,10-PHENANTHROLINES, Synlett, (9), 1997, pp. 1096-1098
A short and convenient synthesis of highly soluble 3,8-dialkyl-4,7-dib
romo-1,10-phenanthrolines is described. These compounds are versatile
key building blocks for the preparation of macrocyclic oligophenanthro
lines with exo-coordination sites.
