Various imidazolylsilane derivatives were synthesized by a trans-silylation procedure between 1-(trimethylsilyl) imidazoles and chlorosilanes. Among them, tris-and tetrakis (imidazol-1-yl) silane compounds reacted smoothly with free carboxylic acids to form the corresponding 1-acylimidazoles, which subsequently underwent condensation with amines to afford carboxamides in good to high yields. These results indicate that novel reagents ...
