手性金属簇合物的合成、结构表征及其反应

Synthesis, Structural Characterization and Reaction of the Chiral Clusters

用潜手性羰基簇合物 ( μ3 S)RuCo2 (CO) 9( 1 )与阴离子金属交换试剂Na[M (CO) 3C5 H4C(O)R][R =H ,CH3,C6 H5 ,C6 H4C(O)OCH3;M =Mo ,W ]在四氢呋喃中回流反应 ,生成一系列新的由四个不同原子组成的不对称四面体簇合物 ( μ3 S)RuCoM (CO ) 8CpCOR .研究了簇合物 ( μ3 S)RuCoMo(CO) 8CpCOCH3的还原反应 .对合成的所有化合物进行了IR、1HNMR、C/H元素分析 ,测定了簇合物( μ3 S)RuCoMo(CO) 8CpCOC6 H5 的单晶结构 .

Several chiral clusters RuCoMo(μ 3 S)(CO) 8C 5H 4C(O)R were synthesized by the thermal reaction of the precursor (μ 3 S)RuCo 2(CO) 9 with functionally substituted cyclopentadienyl tricarbonyl metal complex anions [M(CO) 3(η 5 C 5H 4)C(O)R] -(R=H,CH 3,C 6H 5,C 6H 4C(O)OCH 3;M=Mo,W)in THF. All of these clusters were characterized by C/H elemental analysis,IR and 1H NMR.Crystal structure of the cluster (μ 3 S)RuCoMo(CO) 8CpCOC 6H 5 has also been solved by single crystal X ray diffraction.
