ABSTRACT

Reaction of PPh(2)(o-C(6)H(4))(CH(2)NMeCH)C(60) (1) and (μ-H)(3)Re(3)(CO)(11)(NCMe) in refluxing chlorobenzene affords the monorhenium complex HRe(CO)(3)(η(3)-PPh(2)(o-C(6)H(4))(CH(2)NMeCH)C(60)) (2), and the dirhenium complexes (μ-H)Re(2)(CO)(7)(μ,η(3)-PPh(o-C(6)H(4))(2)(CH(2)NMeCH)C(60)) (3) and (μ-H)Re(2)(CO)(5)(μ-SSOH)(μ,η(5)-PPh(2)(o-C(6)H(4))(CH(2)NMeCH)C(60)) (4). The structures of 2-4 have been determined by an X-ray diffraction study. The oxatrisulfanyl (-SSOH) ligand of 4 likely arises from decomposition of CS(2) on silica gel during the purification processes.
