Trityl thionitrite

Solubility soluble in CH2CI2, CHCI3, CCI4 partially soluble in CsHs, ether insoluble in methanol, ethanol. 

Preparative Methods readily obtained as a green crystalline solid from triphenylmethylmercaptan and various nitrosating agents, methods involving phase-transfer conditions appear to be the best.  

Handling, Storage, and Precaution recrystallized and stored in the dark to prevent possible photolytic decomposition decomposes thermally at ca. 110 °C and may be stored in a refrigerator for several days without detectable decomposition. Trityl thionitrite may be mutagenic4 and skin contact should be avoided. 

Incompatible with alkenes, phosphines, thiols, amines, sulfoxides and as well as various transition-metal salts and complexes. 

As a crystalline and, therefore, chemically well-defined precursor to thiyl and NO radicals, each of which have biological relevance, TTN has been characterized by and

In contrast to the diazirine method outlined above, the reaction of O-acyl thiohydroxamates with trityl thionitrite proceeds via the standard chain mechanism with the tritylthiyl radical as chain carrier, and, as in the case of the Barton nitrite pho-... 

Ethyl nitrite poured on trityl mercaptan (under a Ng-atmosphere, which is kept up throughout the entire operation) at 15°, gently shaken, excess ethyl nitrite allowed to evaporate at room temp., and the resulting ethanol removed in vacuo crude triphenylmethyl thionitrite. Y ca. 100%. F. e. with low yield, also thionitrates, s. G. Kresze and U. Uhlich, B. 92, 1048 (1959). 2-Thia- l,3-diazaadamantanes O...
