Abstract

The reaction of various alkyltin compounds [HSnBu₃ and SnR₄, R=Me, Et, cyclohexyl (Cy)] with cloverite dehydroxylated at 450°C was studied by various methods such as ¹H, ³¹P and ¹¹⁹Sn MAS NMR, ¹³C CP-MAS NMR, infrared spectroscopy, analysis of evolved gases, thermolysis and chemical analysis. All techniques showed that there was a formation of grafted -SnR₃ fragments. However, depending on the size of the organometallic fragment, the grafting reaction did not occur in the same manner: while -SnR₃ (R=Me, Et, n-Bu) fragments were grafted homogeneously over the entire crystal volume, -SnCy₃ fragments were grafted only on the external surface, as previously observed on mordenite. In addition, depending on the size of the R alkyl group, different grafted complex loadings were achieved: for R=Me, up to four -SnMe₃ could be grafted per window aperture, while for R=Et and n-Bu, only one complex could be grafted per window aperture.
