The yellow-orange boratabenzene complex Cb\*Co(3,5-Me 2 C 5 H 3 BNMe 2 ) (1) (Cb\* = C 4 Me 4 ) was readily obtained from [Cb\*Co(NCMe) 3 ]PF 6 and Li(TMEDA)(3,5-Me 2 C 5 H 3 BNMe 2 ). Methanolysis of 1 afforded Cb\*Co(3,5-Me 2 C 5 H 3 BOMe) (2). Complex 2 reacted with MeLi and with BCl 3 to give th
