Highly efficient electron transfer from an active aldehyde ( 2 − ) to [Co II (phen) 3 ] 2+ (phen=1,10‐phenanthroline) occurs following the rate‐determining formation of active aldehydes from 3‐benzylthiazolium salts ( 1 + ) and aldehydes in the presence of DBU to give the corresponding radical intermediates ( 2\. ), which have been characterized by ESR.
