Abstract
An object of the present invention is to provide tetrahedral fine palladium particles having a high degree of shape selectivity, and a process for producing fine metal particles.The present invention provides fine palladium particles comprising particles having a tetrahedral shape in a proportion of 60 to 100% by number of particles; a palladium colloid obtained by uniformly dispersing the fine palladium particles within a solvent; a supported catalyst comprising the fine palladium particles dispersedly supported on the surface of, and/or in the pores of, a carrier comprising at least one of a ceramic, a carbon, and an organic polymer; a process for producing fine metal particles comprising: dissolving a tetranuclear precursor metal complex within a solvent to generate a uniform solution, and shape-selectively generating tetrahedral particles by decomposing the metal complex within the uniform solution; and a process for producing a catalyst, comprising bringing the above colloid into contact with a carrier comprising at least one of a ceramic, a carbon, and an organic polymer. The colloid or the catalyst prepared by supporting the colloid on a carrier exhibits a high level of activity and high selectivity in carbon-carbon bond-forming reactions, hydrogenation reactions and the like.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
