<P>PROBLEM TO BE SOLVED: To provide high purity bis(cyclopentadienyl)magnesium and its process by a simple method. <P>SOLUTION: The high purity bis(cyclopentadienyl)magnesium is characterized in that the content of a manganese atom is at most 0.3 mass ppm, that of a silicon atom is at most 0.1 mass ppm, and that of an aluminum atom is at most 0.1 mass ppm. A process of high purity bis(cyclopentadienyl)magnesium comprises as follows. Dialkylmagnesium shown by General Formula (1) and 2.05-2.18 mol of cyclopentadiene based on one mol of dialkylmagnesium are made to react, then the sublimation purification of the obtained bis(cyclopentadienyl)magnesium is carried out under reduced pressure. In the formula, R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>may be the same or different and denote a 1-6C alkyl group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
