Yield: 99%
Reaction Conditions:
dicarbonyl(cyclopentadienyl)methyliron(II) in N,N-dimethyl-formamide for 24 h;Product distribution / selectivity;UV-irradiation;
Steps:
4
Examples 3 to 13 (Table 2, Run No.2 to No.12); Solutions of eleven monohydrosilanes (other than dimethylphenylsilane) in DMF with 4 mol % of CpFe(CO)2Me iron complex catalyst were prepared as shown in Table 2 and irradiated with ultraviolet radiation under a high-pressure mercury lamp. Reaction was carried out for varying times under the same conditions as in Example 1 except that the amount of iron complex catalyst was changed to 0.5 mmol only when the hydrosilane reactant was triphenylsilane. The results are shown in Table 2 together with the result of Example 1. It is evident from Table 2 that corresponding disilanes were produced in high yields of 50% to 100%.
