摘要:
Reaction of (PNPCy)ReOCl2 (PNPCy = N(SiMe2CH2PCy2)(2)) with Mg and H-2 yields (PNPCy)Re(H)(4), whose unsaturation is demonstrated by its ability to add H-2. "(PNPCy)ReH6" is an equilibrium mixture of a structure where all six H's are on Re and a structure where five H's are on Re and one H is on N. (PNPCy)Re(H)(4) reacts with C2H4 within 10 min at 25 degreesC to give ethane and (PNPCy)ReH(equivalent toC-CH3), together with its ethylene adduct.
