The thiolate bridges of are readily split by a variety of phosphines, phosphites and nitrogen-containing compounds to give , 3>, and , (PR3 = PMe2Ph, PMePh2; P(OR')3 = P(OMe)3, P(OEt)3; L (sterically nonhindering) = pyridine, 3-methylpyridine, isoquinoline, N-methylimidazole, acetonitrile; L' (sterically hindering) = 2-methylpyridine, 2,6-dimethylpyridine, quinoline).With H2 under ambient conditions both and combine reversibly, does not react and 3> (in the presence of free P(OR')3) is converted into 4>. and react with phenylacetylene to give and , respectively, while with C6F5SH forms , and further reaction gives .Although is unreactive towards C6F5SH it combines with PhC2H with loss of C6F5SH yielding .Other reagents which split the bridge are carbon monoxide and t-butyl isocyanide.Products were characterised by 1H and 31P NMR spectroscopy and in many cases were not isolated.
