Abstract
A series of 1-phosphinophospholes 4a-d (R = tert-butyl (a), iso-propyl (b), ethyl (c), phenyl (d)) and their pentacarbonyltungsten complexes 5a-d are synthesized and characterized. The P-31 NMR patterns of both the complexed and free 1-phosphinophospholes follow similar trends. T he X-ray structure of 5a reveals an elongated P-P bond due to steric e ncumbrance, while the geometry of the phosphole moiety is not affected .
