Abstract: A method for producing an oligosilane which includes a reaction step of producing an oligosilane by dehydrogenative coupling of hydrosilane. The reaction step is carried out in the presence of a catalyst containing at least one transition element selected from the group consisting of Periodic Table group 3 transition elements, group 4 transition elements, group 5 transition elements, group 6 transition elements, and group 7 transition elements. Also disclosed is a method for producing a catalyst for dehydrogenative coupling that produces an oligosilane by dehydrogenative coupling of hydrosilane.

Abstract: An object of the present invention is to provide an oligosilane production method with which a target oligosilane can be selectively produced. Oligosilanes can be efficiently produced at an improved selectivity for a target oligosilane by using, as a raw material, not only monosilane but also an oligosilane with a smaller number of silicon atoms than the target oligosilane or conversely an oligosilane with a larger number of silicon atoms than the target oligosilane.

Abstract: An object of the present invention is to provide a method for producing oligosilane and in particular to provide a method that can efficiently produce oligosilane at lower temperatures and with an improved yield and selectivity. In the dehydrogenative coupling reaction of hydrosilane, oligosilane can be efficiently produced at an improved selectivity for oligosilane, and in particular at an improved selectivity for disilane, by carrying out the reaction in the presence of zeolite having pores with a minor diameter of at least 0.43 nm and a major diameter of not more than 0.69 nm.
