Abstract
Abstract Inelastic electron tunnelling spectroscopy (IETS) has been used to study the reaction of 5-bromo-2-hydroxybenzaldehyde with monomolecular layers of 3-aminopropyltriethoxysilane and 3-(2-aminoethyl)aminopropyltrimethoxysilane immobilized on aluminium oxide surfaces. It is concluded from the spectra that the terminal amino group of both silanes condenses with the aldehyde group of the aromatic molecule to form the corresponding 5-bromo-2-hydroxybenzaldimine derivative. Neutron activation and ESCA experiments support this conclusion.
