Sažetak
By monitoring of solvent-free benzoylation reactions of 2-naphthol and 2, 3-naphthalenediol with p-methylbenzoyl chloride by continuous IR spectral measurements in Nujol mulls, reaction pathways were almost completely clarified. The monitoring experiments suggest a formation of inclusion complex between napththol and its benzoate as an intermediate. The inclusion complex which was prepared by a separate experiment was found to be identical to the intermediate estimated by the spectral measurement. Since the inclusion complex is stable against a further benzoylation reaction, it is necessary to heat the reaction mixture for to complete the reaction. Reason of the stability of the complex was clarified by its X-ray analysis. Hydrogen bond networks in the complex are important for the stabilization.
