In situ diffuse reflectance infrared investigations of coadsorption and intrazeolite reactions of hexacarbonyl molybdenum(0) and organic ligands

Abstract

Diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) investigations indicate that under thermal activation, the coadsorption, by vapour-phase loading, of Mo(CO)₆ and C₆H₆ or C₆H₅N in the Na₈₅X faujasite-type zeolite leads to the grafted Mo(CO)₃ moiety, whereas (η⁶-C₆H₆) Mo(CO)₃ and (C₅H₅N)_x Mo(CO)_{6 –x}(x= 1,2,3) are obtained in Na₅₅Y; no reaction is observed in the dealuminated Y* zeolite before the desorption.
