Abstract
The ring-opening reaction of(S)-1-phenylspiro[2,4]hepta-4,6-diene with LiPP h2 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 c omplexes of rhenium, rhodium, zirconium, and iron with this new chiral bide ntate ligand have been prepared; additionally, the X-ray crystal structure of (S)-[Rh(eta(2)-C2H4)(eta(5)-C5H4-CH2CHPhPPh2-kappa P)] is reported.
