通过4-甲氧基苯硒酚和2-甲基苯硒酚分别与Co(PMe34反应生成了单核Co(II)配合物[Co(4-MeOC6H4Se)2-(PMe33](1)和双核Co(I)配合物[Co(PMe32(SeC6H4-2-Me)]22).配合物2与CO作用形成了配合物[Co(PMe32(CO)2(Se-C6H4-2-Me)](3).而苯硒酚与Co(PMe34反应制备了硒配位的钴氢配合物[mer-Co(H)(SePh)2(PMe33](4)和双核Co(I)配合物[Co(PMe32(SePh)]25).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134的分子结构通过X射线衍射进行了证实.

A mononuclear cobalt(II) complex[Co(4-MeOC6H4Se)2(PMe3)3] (1) and a dinuclear cobalt diphenylselenolato complex[Co(PMe3)2(SeC6H4-2-Me)]2 (2) were obtained from the reaction of 4-methoxyselenophenol and 2-methylseleno-phenol with Co(PMe3)4, respectively. The dicarbonyl cobalt(I) complex[Co(PMe3)2(CO)2(SeC6H4-2-Me)] (3) was formed through the reaction of complex 2 with carbon monoxide. A novel selenophenolato hydridocobalt(III) complex[mer-Co(H)(SePh)2(PMe3)3] (4) and a dinuclear cobalt diphenylselenolato complex[Co(PMe3)2(SePh)]2 (5) were synthesized by the reaction of selenophenol with Co(PMe3)4. It was found that complex 4 could catalyze the hydrosilylation of aldehydes and ketones. The molecular structures of 1, 3 and 4 were determined by X-ray diffraction.

Key words: hydrido cobalt complex, selenophenol, Se-coordinated, hydrosilylation, carbonyl cobalt complex
