Three tertiary stibines containing tetrachloropyridyl groups, tris(2,3
,5,6-tetrachloro-4-pyridyl)stibines, phenyl- and tolylbis(2,3,5,6-tetr
achloro-4-pyridyl)stibines and their dibromides, were synthesized. The
compounds were characterized by elemental analysis, vapour pressure o
smometry, thermogravimetry, IR, far IR, H-1 and C-13 NMR spectroscopy.
IR and NMR data indicate that the tetrachloropyridyl group is attache
d to antimony through the fourth position.
