Abstract

New bis(phosphinoamine) and bis(phosphinite) derivatives of 2,2'-bipyridine were prepared through a single step reaction of 3,3'-diamino-2,2'-bipyridine or 3,3'-dihydroxy-2,2'-bipyridine with diphenylehlorophosphine, respectively. Their P = E chalcogenides (E = 0, S, Se) were also prepared. All the new compounds were characterized by elemental analysis, IR and NMR spectroscopies. The molecular structure of 3.3'-bis(diphenylthiophosphinite)-2,2'-bipyridine was elucidated by single-crystal X-ray crystallography. (c) 2007 Elsevier Ltd. All rights reserved.
