A mononuclear iron bivalent complex having iron-silicon bonds, which is represented by formula (1), can exhibit an excellent catalytic activity in at least one reaction selected from three reactions, i.e., a hydrosilylation reaction, a hydrogenation reaction and a reaction for reducing a carbonyl compound.
(In the formula, R1 to R6 independently represent a hydrogen atom, an alkyl group which may be substituted by X, or the like; X represents a halogen atom, or the like; L1 represents at least one two-electron ligand selected from an isonitrile ligand, an amine ligand, an imine ligand, a nitrogenated heterocyclic ring, a phosphine ligand, a phosphite ligand and a sulfide ligand, wherein, when multiple L1's are present, two L1's may be bonded to each other; L2 represents a two-electron ligand that is different from a CO ligand or the above-mentioned L1, wherein, when multiple L2's are present, two L2's may be bonded to each other; and m1 represents an integer of 1 to 4 and m2 represents an integer of 0 to 3, wherein the sum total of m1 and m2 (i.e., m1+m2) satisfies 3 or 4.)
具有铁-硅键的单核二价铁络合物,其由公式(1)表示,可以在三个反应中选择至少一个反应表现出优异的催化活性,即硅氢化反应、氢化反应和还原羰基化合物的反应。
(在公式中,R1至R6独立代表氢原子、可能被X取代的烷基团等;X代表卤素原子等;L1代表至少一种从异腈配体、胺配体、亚胺配体、氮杂环、膦配体、亚磷酸盐配体和硫化物配体中选择的两电子配体,其中,当存在多个L1时,两个L1可以相互连接;L2代表与CO配体或上述L1不同的两电子配体,其中,当存在多个L2时,两个L2可以相互连接;m1代表1至4的整数,m2代表0至3的整数,其中m1和m2的总和(即m1+m2)满足3或4。)
