A metal-free protocol of direct C(sp3)–H cyanation with cyanobenziodoxolones functioning as both cyanating reagents and oxidants was developed. Unactivated substrates, such as alkanes, ethers and tertiary amines, were thereby transformed to the corresponding nitriles in moderate to high yields. Mechanistic studies indicated that the cyanation proceeded with two potential pathways, which is highly dependent

general, high-yielding amine Cα–H cyanation protocol via photoredox catalysis. Inexpensive NaCN is employed as the cyanidesource and air is the external oxidant, resulting in mild and highly functional group tolerant conditions. Notably, efficient Cα–H cyanations of secondary and tertiary aliphatic amines and of complex, biologically active compounds (drugs) can be performed using the established methodology

A fit catalyst for some aerobic exercise: A manganese oxide‐based octahedral molecular sieve, OMS‐2, could act as an efficient heterogeneous catalyst for the regioselective α‐cyanation of various tertiaryamines, including trialkyl, benzylic, and N,N‐dialkylaniline derivatives using trimethylsilyl cyanide (TMSCN) as the cyano source and molecular oxygen as the terminal oxidant.
