Synthesis of Potentially Catalytic Bimetallic Systems.

摘要

Work this year has focused on the development of a synthetic sequence to the double metal system shown in Figure XIV which incorporates ferrocene as the backbone of the molecule. Such systems have the potential for hydrogen evolution from acidic solutions. A route to the synthesis of 1'-benzylferrocenecarbinol (XIII), involving the diketone intermediate 1-benzoyl-1'-o-chlorobenzoyl-ferrocene (XXIII) is discussed. XIII is used to synthesize the novel double metal compounds 1'-benzylferrocenecarbinol chromium tricarbonyl (XXIX,M=Cr) and 1-methylenediphenylphosphite-1'-benzylferrocene chromium tricarbonyl (XXX,M=Cr). An analogous compound, benzylferrocene chromium (XXX,M=Cr) triphenylphosphine dicarbonyl (XXXIII) was also prepared. (Author)
