Abstract
Abstract The reaction of the bis(triflates) 1,2-bis[2-(trifluoromethylsulfonyloxy)ethyl]benzene (1), 1,2-bis[3-(trifluoromethylsulfonyloxy)propyl]benzene (3) and 1,2-bis{2-[2-(trifluoromethylsulfonyloxy)ethyl]phenyl}ethane (6), respectively, with the carbonyl metalates [M(CO)4]2- (M=Os (a), Ru (b), Fe (c)) results in the formation of the osmaorthocyclophanes 2a, 4a, 7a and 8a, the ruthenacylophane 2b and the ferracyclophanes 2c and 7c, respectively. Carbon monoxide insertion into the Fe-Cσ bonds of the ferracycles 2c and 7c, respectively, affords the ketones 3-oxo[5]orthocyclophane (9) and 3-oxo[5.2]orthocyclophane (11). The structure of 2a was investigated by an X-ray structural analysis. 2a crystallizes in the monoclinic space group P21/n with Z=4.
