Here we report a new chemical reagent for transnitrosation under mild experimental conditions. This newreagent is stable to air and moisture across a broad range of temperatures and is effective for transnitrosation in multiple solvents. Compared with traditional nitrosation methods, our reagent shows high functional group tolerance for substrates that are susceptible to oxidation or reversible transnitrosation

nitrosation was never observed, but minor amounts of m- and p-nitro amines and/or nitrosamines were formed in some cases. Ring nitration is rather a reaction of the initial substrate than a process occurring on formed nitrosamines. The leaving propensities of the initial N-substituents to yield nitrosamines were in the order benzylmethyl alkyl.
aryl N-nitrosamines to secondary amines is reported under metal-free conditions using iodine and triethylsilane. Several reduction-susceptible functional groups such as alkene, alkyne, nitrile, nitro, aldehyde, ketone and ester were found to be very stable during the denitrosation, which is remarkable. Broad substrate scope, roomtemperature reactions and excellent yields are the additional features

reported for the denitrosation of aryl-N-nitrosamines under mild reaction conditions using ethanethiol and PTSA. The reactions proceeds at roomtemperature and the amines are obtained in good to excellent yields. Many functional groups that are susceptible to reduction were stable during the denitrosation. A broad substrate scope and easy operations are salient features of this method.
