Methods for oligomerizing olefins

It includes that the present invention offers the method of oligomer-izing of an olefin, and makes an olefin react to a catalyst under oligomer-ized conditions. A catalyst may be a クロミウム compound and pyridyl amine, or the product in which the ヘテロア reel amine compound was put together. In the mode of characteristic enforcement, the catalyst compound can use ethylene for 3 quantification or quantifying four times and making it 1* hexene, 1* オクテン, or these mixtures.
