Oragno tin precursors for synthesis of zeolite Sn-Beta for alcohol ring opening of epoxides Lewis acid zeolite Sn-Beta is hydrothermally synthesized using alkyl tin precursors. NMR experiments indicate that alkyltin precursors affect the site formed with methyl tin trichloride increasing the fraction of open defect sites. Catalytic testing showed that the open defect sites are highly active for the epoxide ring opening with methanol.
