Compounds of the formula Et4N[Re2(μ-SR)3(CO)6], (R Me, But, Ph, C6F5) may be prepared in good yields from reactions between various halocarbonylrhenate anions and either the thiolate anion or (n-Bu)3SnSR. These stable, white or off-white, Crystalline species undergo reactions with [Me3O]BF4 in the presence of phosphines to form cis-Re2(μ-SR)2(CO)6(L)2 (L PMe3, PPh3, 12 dppm). When heated in benzene
式Et 4 N [Re 2(μ-SR)3(CO)6 ],(RMe,Bu t,Ph,C 6 F 5)的化合物可以由各种卤代羰基金属酸根阴离子与硫醇根阴离子或(n-Bu)3 SnSR。这些稳定的白色或类白色结晶物质在膦存在下与[Me 3 O] BF 4反应,形成顺式-Re 2(μ-SR)2(CO)6(L)2(LPMe 3,PPH 3,12 dppm)。当在苯中加热时,这些化合物会转化为反式异构体。相反,当它们在四氢呋喃中加热时,一氧化碳会流失,并且会分离出Re 2(μ-SR)2(μ-CO)(CO)4(L)2物质。
