Aldehydes in excellent yields were obtained from the ruthenium–porphyrin‐catalyzed oxidation of various terminal alkenes with 2,6‐dichloropyridine N ‐oxide under mild conditions. The aldehydes generated from these ruthenium‐catalyzed alkene oxidations can be used in situ for olefination reactions with ethyl diazoacetate in the presence of PPh 3 in a one‐pot diazoacetate olefination starting from alkenes (see example).
