Early/late bimetallic complexes: MCo2 (MTi, Zr) derivatives

Abstract (η 5 -C 5 H 5 ) 2 M[Co(CO) 4 ] 2 (MTi, Zr) complexes were prepared by alkane elimination from the corresponding metallocene diorganyls and HCo(CO) 4 or by salt elimination from metallocene dihalides and Na[Co(CO) 4 ]. (Ph 2 N) 2 Ti[Co(CO) 4 ] 2 was obtained from (Ph 2 N) 4 Ti and HCo(CO) 4 .
