摘要

The heterometallic complex [TiCp*(O(2)Bz)(2)AlMe2] (2) has been synthesised by reaction of [TiCp*(O(2)Bz)(OBzOH)] (1) with A]Me, (Cp*=eta(5)-C5Me5; Bz=benzyl). Complex 1 reacts with HOTf to yield the cationic derivative [TiCp*-(OBzOH)(2)]OTf (3) (HOTf=HSO3CF3). Compound 3 reacts with [{M(mu-OH)(cod)}(2)] (M = Rh, Ir; cod = cyclooctadiene) to render the early-late heterometallic complexes [TiCp*(O(2)Bz)(2)(M(cod)}(2)]OTf (M=Rh (4); Ir (5)). The molecular structure of complex 4 has been established by single-crystal X-ray diffraction studies.
