Notes:
The reaction of the ortho-, meta-, and para-bis(triflates) [(F3CSO2OCH2CH2C6H4)2(CH2)n] with n = 0 (ortho: 1a), n = 0, 1 (meta: 1b, d), and n = 0-2 (para: 1c, e, g) with [Os(CO)4]2- results in the formation of the diosma[5.n.5.n]-ortho-, -meta-, and -paracyclophanes with n = 0 (ortho: 2a), n = 0, 1 (meta: 2b, d), and n = 0-2 (para: 2c, e, g). On reaction of the bis(triflates) 1a, b with the dianionic [Fe(CO)4]2- the corresponding ferracyclophanes are formed only in situ. Carbon monoxide insertion into the Fe-C s̰ bonds of the ferracycles affords the ketones 6a, b. The structures of 2a and 2e were investigated by X-ray structural analysis. Compounds 2a and 2e crystallize in the space group P21/c with Z = 8 and P1 with Z = 2, respectively.
