Process for producing aminosilane compounds

Claim 1

A process for producing an aminosilane compound represented by the general formula (1) described below, which comprises carrying out steps (A), (B) and (C) in this order without an intervenient isolation nor purification treatment: (A): reacting a compound having a cyclopentadiene skeleton with a strong base; (B): reacting the reaction product obtained in the step (A) with a silane compound represented by the general formula (2); and (C): reacting the reaction product obtained in the step (B) with an amine compound represented by the general formula (3) or an alkali metal amide compound represented by the general formula (4); ##STR4## wherein, for the respective general formulae (1), (2), (3) and (4), Cp represents a group having a cyclopentadiene skeleton; M represents an alkali metal atom; R 1 and R 2 independently represent a hydrogen atom, an alkyl group, an aralkyl group, an aryl group or a substituted silyl group; R 3 and R 4 independently represent an alkyl group, an aralkyl group, an aryl group, a substituted silyl group, an alkoxy group, an aralkyloxy group or an aryloxy group; (R 1 and R 2 ) and/or (R 3 and R 4 ) may be linked to form a ring; and X 1 and X 2 independently represent a halogen atom.
