Staudinger predicted a correlation between the physical properties of a polymer and its main-
chain stereochemistry as early as 1929. 1 However it was not until 1947 that Schildknecht …

Iron (Fe) is considered to be one of the most significant elements due to its wide
applications. Recent years have witnessed a burgeoning interest in Fe catalysis as a …
