摘要：

The ring-opening reaction of (S)-1-phenylspiro[2,4]hepta-4,6-diene with LiPPh2 proceeds with full regio- and stereoselectivity, taking place at phenyl-substituted carbon and with complete inversion of the configuration at the stereogenic center, yielding (S)-[Li(C5H4CH2CHPhPPh2)]. Optically active complexes of rhenium, rhodium, zirconium, and iron with this new chiral bidentate ligand have been prepared; additionally, the X-ray crystal structure of (S)-[Rh(η2-C2H4)(η5-C5H4CH2CHPhPPh2-κP)] is reported.
