been developed. This approach employs an earth-abundant and inexpensive manganese complex, Mn2 (CO)10 , as the catalyst and visible light as the energy input. Using this strategy, site-selective chlorination of unactivated C(sp3 )-H bonds of aliphatic amines and intramolecular/intermolecular chloroaminations of unactivatedalkenes were readily realized under mild reaction conditions, thus providing efficient

New reaction conditions for the rapid and productive intermolecularaminochlorination reaction of alkenes using a combination of chloramine‐T and a Brønstedt acid are described. Upon simple protonation of chloramine‐T, conditions for a mild and selective aminochlorination are obtained. In addition, the reaction can proceed to form either of the two possible regioisomers, depending on whether a stoichiometric

reacts N-chloramines directly, avoiding purification and isolation steps. 2-Chloramines were produced from the reaction of styrenes with N-alkyl-N-sulfonyl-N-chloramines, whilst N-alkyl or N,N'-dialkyl-N-chloramines reacted with anisaldehyde in the presence of t-BuO2H oxidant to afford amides. Primary and secondary imines were produced under continuous conditions from the reaction of N-chloramines with
