Abstract: The compositions of the present invention comprise one or more palladium bound ligands that are covalently bonded to inorganic or organic solid supports. These palladium bound ligands bonded to solid supports can be used for single heterocyclic amine base separation, or can be used to separate nucleotide chain containing specific sequences from other nucleotides or nucleotide chains. In one aspect of the invention, each ligand present is individually complexed to a single Pd(II) ion. If there are from 2 to 4 ligands present in the composition, then each ligand present must be separated from the other ligands by at least 3 atoms, preferably from 3 to 20 carbon atoms or equivalent spacing.

Abstract: The invention has compositions of matter and process aspects.The compositions of matter aspect relate to two classes of new organic compounds, viz., A. intermediates which are sulfur-containing hydrocarbons covalently bonded to trialkoxysilane and B. that class of intermediates covalently bonded to an inorganic matrix, e.g., silica, silica gel, glass, glass fibers, alumina, nickel oxide, zirconia, and titania. The process aspect comprises two processes, viz., (1) a process for making the two new classes of compounds A and B, and (2) the process of removing and concentrating certain ions, such as noble metal ions and other transition metal ions, from solution thereof admixed with other ions which may be present in much higher concentrations by forming a complex of the desired ion(s) with a compound of class B, e.g., by flowing the solution through a chromatography column packed with the compound, breaking the complex, e.g.
