Azodesilylation - a Novel Aprotic Diazotization Technique

Weiss, Robert,Wagner, Klaus-Georg,Hertel, Marion

, p. 1965 - 1972 (2007/10/02)

Nitrosyl compounds NOA (4a - e, A = Cl, Br, BF4, CF3SO3, I) - generated partially in situ from O = N - OR/(CH3)3SiA (7a, b, R = iC5H11, C2H5/8a, b, e, A = Cl, Br, I) - react in aprotic organic media with N,N-bissilylated organylamines RN2 (3b, R = C6H5; 15, R = CH3) under generation of diazonium systems R - N2+ A- and formation of non-nucleophilic hexamethyldisiloxane (6b).This method represents the first nucleophile excluding diazotization technique on the basis of three-coordinated nitrogen and is termed "azodesilylation".
