Yx. Wang et Dp. Rillema, ALTERING THE REACTION PATHWAYS OF AMINOPYRIDINE WITH 4,5-DIAZAFLUORENONE - METAL-ION CONTROL, Tetrahedron letters, 38(38), 1997, pp. 6627-6630
A parallel study of the ligand 4,5-diazafluorenone reactivity in the p
resence and absence of ruthenium(II) ion revealed that the reaction pa
thway of the ligand 4,5-diazafluoren-9-one with aminopyridine can be a
ltered from the normal Schiff-base reaction to an unusual ring opening
reaction upon its coordination to ruthenium(II) ion. (C) 1997 Elsevie
