It is demonstrated for the first time that the site‐selectivity for the Fe + ‐mediated CH bond activation of aldimines R 1 NCHR 2 (R 1 , R 2 = alkyl) involves the alkyl chain R 1 by a factor ≥ 12 in comparison to the alkenyl part R 2 . This finding explains previous observations that dehydrogenation of intermediates formed by alkene loss from either R 1 or R 2 of R 1 NCHR 2 /Fe + preferentially involves the alkyl part.
