The reaction of Co2(CO)8 with RCCSF5 gives 1 : 1, 1 : 2, and 1 : 3 type products, depending on R. For R = H all three products can be isolated. According to the single-crystal structure determinations, the 1 : 1 product has the known di-cobaltatetrahedrane structure, the 1 : 2 product is a cobaltacyclopentadienecobalt, whereas the 1 : 3 product has been previously identified as a “fly-over bridge”
CO 2(CO)的反应8与RCCSF 5给出了1:1,1:2和1:3级型的产品,这取决于R.对于R = H所有三种产品可被分离。根据单晶结构测定,1:1产物具有已知的二钴四面体结构,1:2产物为钴环戊二烯钴,而1:3产物先前已被鉴定为“飞越桥”复杂的。位更拥挤˚F 3 CCCSF 5和C 6 H ^ 5 CCSF 5只给出1:1反应。F的产物3 CCCSF 5分发生反应进一步用HCCSF 5 制成由不同炔烃分子组成的1:3产物。
