, p. 454 - 459 (2013)
The hydrosilylation reaction of ethylene with triethoxysilane catalyzed by ruthenium halides and promoted by cuprous halides, iodine or ferrous chloride tetrahydrates was conducted at temperatures ranging from 30 to 80 C under a mild pressure of ethylene gas. Ruthenium chloride trihydrates and cuprous chloride are proved to be the best catalyst and promoter for this reaction. With the addition of 6.8 × 10-5 mol ruthenium chloride trihydrates per mole of triethoxysilane together with over 3 times of cuprous chloride per mole of ruthenium chloride trihydrates, the reaction can conduct rapidly at temperatures ranging from 40 to 60 C under a pressure of ethylene gas lower than 0.35 MPa with over 96% yield of ethyltriethoxysilane within 6 h.

Paragraph 0215-0217, (2016/12/01)
Provided is a mononuclear iron complex that comprises an iron-silicon bond that is represented by formula (1) and that exhibits excellent catalyst activity in each of a hydrosilylation reaction, a hydrogenation reaction, and reduction of a carbonyl compound. In formula (1), R 1 -R 6 either independently represent an alkyl group, an aryl group, an aralkyl group or the like that may be substituted with a hydrogen atom or X, or represent a crosslinking substituent in which at least one pair comprising one of R 1 -R 3 and one of R 4 -R 6 is combined. X represents a halogen atom, an organoxy group, or the like. L represents a two-electron ligand other than CO. When a plurality of L are present, the plurality of L may be the same as or different from each other. When two L are present, the two L may be bonded to each other. n and m independently represent an integer of 1 to 3 with the stipulation that n+m equals 3 or 4.
