The Surface of Inorganic Oxides or Zeolites as a Nonconventional Reaction Medium for the Selective Synthesis of Metal Carbonyl Complexes and Clusters

摘要

The practice of carrying out reactions in solution may reflect tradition,~1 but it appeared in the last two decades that one can carry ut many organic reactions on solids~(1-6) (alumina,~(1-4) silica,~2-4 zeolites,~5 clays,~5,6 and polymers~2,3), generating faster reactions and higher yields than via the traditional solution methods.~1 Recently the surface of inorganic oxides also proved to be a useful reaction medium for the easy high-yield preparation of various metal carbonyl complexes and clusters~7-9a which are of interest as catalysts or catalysts precursors.~9b-g
