The amino(methylene)borane 1 can be complexed as an η 2 and as an η 5 ligand. Whereas TiCl 4 coordinates in an η 5 fashion to the five‐membered ring ( 2 ) with transfer of a Cl atom to the B atom, reaction of 1 and Fe 2 (CO) 9 gives compound 3 containing an FeBC ring; in 3 , Fe is coordinated in a distorted trigonal‐bipyramidal fashion.
