Synthesis, structure, and reactivity of (η5: η1-C5Me4(CH2) 2NMe2)Re(CO)2. Electron transfer behavior of a nitrosyl derivative
The UV irradiation of a hexane solution of the complex (η5- C5Me4(CH2)2NMe2)Re(CO) 3 (1) afforded the chelated species (η5: η1-C5Me4(CH2) 2NMe2)Re(CO)2 (2). The molecular structure of 2 has been determined by X-ray crystallography. The reaction of 2 with two-electron donor ligands yields (η5-C5Me 4(...
