Endohedral metallocenophanes of rhodium and cobalt

The synthesis of seven endohedral metallocenophanes of rhodium (7b, 8b) and cobalt (1d-h) with a cyclopentadienyl unit as one of the π-systems and a cyclobutadiene or cyclopentadienone unit as the second π-system is described, including the synthesis of the unsubstituted parent compound of the [CpCo(cbd)]-derived endohedral phanes, [3.3]-η5-(1,1′,3, 3′)-cyclopentadienyl-η4-(cyclobutadienophane)cobalt(I) (1h). This compound could be obtained by deprotection of the corresponding trimethylsilyl-substituted endohedral phane 1g. The X-ray structures of 7b, 1e, 1g and 1h could be obtained. This paper compares their structural properties to the complexes reported in previous short communications.
