通过4-甲氧基苯硒酚和2-甲基苯硒酚分别与Co(PMe_3)_4反应生成了单核Co(Ⅱ)配合物[Co(4-MeOC_6H_4Se)_2-(PMe_3)_3](1)和双核Co(Ⅰ)配合物[Co(PMe_3)_2(SeC_6H_4-2-Me)]_2(2).配合物2与CO作用形成了配合物[Co(PMe_3)_2(CO)_2(SeC_6H_4-2-Me)](3).而苯硒酚与Co(PMe_3)_4反应制备了硒配位的钴氢配合物[mer-Co(H)(SePh)_2(PMe_3)_3](4)和双核Co(I)配合物[Co(PMe_3)_2(SePh)]_2(5).初步研究表明4对于醛和酮的硅氢化反应有一定的催化效果.配合物1,3和4的分子结构通过X射线衍射进行了证实.
The mononuclear Co (Ⅱ) complex [Co (4-MeOC_6H_4Se) _2- (PMe_3) _3] was synthesized by the reaction of 4-methoxyphenylselenophenol and 2-methylselenophenol with Co (PMe_3) 1 and Co (PMe_3) _2 (SeC_6H_4-2-Me)] _2 (2). The complex 2 [CO (PMe_3) _2 (CO) _2 (3). The reaction between selenol and Co (PMe_3) _4 to prepare the selenium coordinated cobalt-hydrogen complex [mer-Co (H) (SePh) _2 (PMe_3) _3] ) And dinuclear Co (I) complex [Co (PMe_3) _2 (SePh)] _2 (5) .Preliminary studies show that 4 has a certain catalytic effect on the hydrosilylation of aldehydes and ketones. The molecular structure was confirmed by X-ray diffraction.
