文摘

Minute stoichiometric bimetallic clusters rich in tin (PtSn₂, RhSn₂, and RuSn₂) are powerful selective hydrogenation catalysts: these “molecular metallic” entities, supported on mesoporous silica and characterized by aberration-corrected electron microscopy, yield high percentages of cyclododecene (CDE) at fractional conversions ranging from 0.45 to 0.70 of the parent cyclododecatriene (CDT) at modest temperatures and under solvent-free conditions.
