A Novel Route to Tris(silatranyloxy-i-propyl)amine
Directly from Silica and Triisopropanolamine, Part I
Pensri Piboonchaisita, Sujitra Wongkasemjita,* and Richard M Laineb
ABSTRACT: New convenient and inexpensive method of tris(silatranyloxy-i-propyl)amine synthesis
directly from silica and triisopropanolamine (TIS) has been elaborated using ethylene glycol solvent.
The silatrane product is obtained in one step via the the "Oxide One Pot Synthesis (OOPS)" process. In
the presence of catalytic amounts of triethylenetetramine (TETA), the reaction easily takes place. The
product is characterized by DSC, TGA, 1H-, 13C-, 29Si-NMR and FAB+-MS. The FTIR result indicates the
presence of NYSi transannular bonding. The chemical and physical properties of these compounds are
described specially with respect to their polymeric properties.
