Embodiment 1
[0024] In a 500mL round bottom flask, add α-hexadecene 134.66g (0.6mol) and trimethoxysilane 75.76g (0.62mol), then add the catalyst carbonyl ruthenium chloride [RuCl 2 (CO) 3 ] 2 1.0mL of 1,4-dioxane solution (wherein, the ruthenium content is 3000mg / L) constitutes the reaction system, the concentration of ruthenium in the reaction system is 14.19mg / kg, stirring reaction under 35 ℃, after 76 hours, the reaction The GC detection results of the liquid showed that the composition of the reaction system did not change any more, the GC-FID area normalized content of the β addition product was 81.27%, and the other compositions were trimethoxysilane 0.03%, tetramethoxysilane 1.82%, Non-α hexadecene 3.47%, α-hexadecene 0.65%, hexadecane 0.27%, α addition products and other addition product isomers 5.81%.
Embodiment 2～10
[0026] Add α-hexadecene 134.66g (0.6mol), change the type and amount of alkoxyhydrogensilane, the type and amount of catalyst, reaction temperature, one or more conditions in the reaction time, other operations are the same as in Example 1 , The GC-FID area-normalized content of the β-addition products is listed in Table 1.
