がりその出現が要望されていた。However, in the above-mentioned conventional method, when M 2 PtCl 4 or M 2 PtCl 6 is used, it is necessary to remove the halogen, which becomes a catalyst poison, and the process is complicated, and the removal is difficult. If not, the performance was degraded. Furthermore, M 2 PtCl 4 and M 2 PtCl 6 (M =
H) and [Pt (NH 3 ) 4 ]. (NO 3 ) 2 are strongly acidic,
Since [Pt (NH 3 ) 4 ]. (OH) 2 is strongly alkaline, there is a problem that the carrier is limited. Further, although the platinum compound is water-soluble, if it is a compound that is also soluble in an organic solvent, its application range is further widened such as non-aqueous catalyst preparation, and its appearance has been demanded.
