Reactions of dinuclear metal carbonyl .alpha.-diimine complexes with alkynes. Part 2. Selective coupling of an .alpha.-diimine ligand and CO and methyl propynoate molecules to give Fe2(CO)n{(R)N:C(H)C(H)N(R)C(O)C(H):CC(O)OMe}, containing a flyover-type ligand and showing a reversible CO-induced metal-metal bond fission with x-ray crystal structures (n = 5, R = i-Pr; n = 6, R = c-hex)
