摘要：

The reaction of [Cp*Co(mu-CO)]2(CO = CO) (1) with AS4 in boiling toluene gives the cobalt complexes [Cp*Co(CO)(eta1:1-AS4)] (2), [{CP*CO(CO)}2(mu-eta1:1:1:1-As4)] (3), exo,endo-[Cp*Co(mu4:1:1-AS4)Co(CO)CP*] (4a, b), and [Cp*Co(mu-eta2:2-As2)]2 (5), CP* = C5Me5. 2,3, and 4b have been characterized by X-ray structure analyses. With respect to the mechanism of this reaction the successive cleavage of two, three, and four As-As bonds of yellow arsenic, As4, has been proved.
