Sodium tetracarbonylferrate anhydrides

An alternative route to aldehydes from carboxylic acids involves conversion of the acid into the carboxylic ethylcarbonic anhydride (1) by reaction with ethyl chloroformate. These anhydrides react with sodium tetracarbonylferrate... 

Carboxylic acid triethylamine salts yield mixed anhydrides which, when treated with ethoxymagnesiomalonic esters give the benzoylated malonate. Alternatively, treatment of the mixed anhydrides with sodium tetracarbonylferrate(II) produces the aldehyde derived from the parent aliphatic or aromatic carboxylic acid in good yield. ...
