Abstract

The synthesis of a new series of trimethoxysilyl-tethered N-substituted 3,5-dialkylpyrazolylpyridines is reported. The silyl spacers allow the grafting of ligands onto silica via formation of covalent bonds as well as the synthesis of xerogels.

Key words

heterocycles - ligands - pyridines - pyrazoles - silicon
