Synthesis and coordination of 2-diphenylphosphinothiophenocarboxamide and bis(2,5-diphenylphosphinepicolinamide)
摘要:
2-Diphenylphosphinothiophenocarboxamide (dpptc) and bis(2,5-diphenylphosphinepicolinamide) (bdpppa) have been prepared and complexed with a variety of metals. Bdpptc behaves as a monodentate P donor ligand and can become bidentate by making use of the C=O site. Bdpppa behaves as a P donor bridging ligand. In many cases, the X-ray structures reveal that the ligand backbone geometry is strongly influenced by intramolecular H-bonding. (C) 2004 Elsevier Ltd. All rights reserved.
