The acid-catalysed reaction of the diyne complex [(Co2(CO)6)2(μ-η2:μ- η2-HOCH2C2C2CH 2OH)] with a range of dithiols leads in each case to the formation of at least two cyclic products, a monomeric product [(Co2(CO)6)2(μ-η2:μ- η2-SCH2C2C≡CCH2SR)] and a dimeric product [(Co2(CO)6)2(μ:η2:μ: η2-SCH2C2C2CH 2SR)]2, [R = (CH2)n (n = 3-6)]. This method may also be applied to dithiols that contain additional donor atoms such as S or O to give crown type macrocycles. The crystal structures of several of the above new complexes are reported.
