Abstract
The reactions of hexachlorocyclotripho‐sphazatriene, N~3~P~3~Cl~6~ (1), with 2‐hydroxypyridine (2), 2‐aminopyridine (3), 2‐amino‐6‐methyl‐pyridine (4), and 2‐hydroxy‐4‐methylquinoline (5) have been investigated. The products were identified by elemental analyses, IR, ^1^H, ^13^C, and ^31^P NMR spectroscopy. © 2006 Wiley Periodicals, Inc.
