钌配合物(IMesH(2))(Cl)(2)(C5 H5 N)(2)Ru=CHPh [IMesH(2)= 1,3-dimesityl-4,5-dihydroimidazol-2-ylidenel(3)]由(IMesH(2))(PCy 3)(Cl)(2)Ru=CHPh(2)与过量吡啶反应制得。配合物3含有取代不稳定的吡啶和氯化物配体,并作为合成新的钌亚苄基的通用起始材料。
The ruthenium complex (IMesH(2))(Cl)(2)(C5H5N)(2)Ru=CHPh [IMesH(2) = 1,3-dimesityl-4,5-dihydroimidazol-2-ylidenel (3) was prepared by the reaction of (IMesH(2))(PCy3)(Cl)(2)Ru=CHPh (2) with an excess of pyridine. Complex 3 contains substitutionally labile pyridine and chloride ligands and serves as a versatile starting material for the synthesis of new ruthenium benzylidenes.
