N,N,N¢, or trichloromelamine (TCM) were used as effective oxidizing agents for the oxidation of urazoles and bisurazoles to their corresponding triazolinediones under mild and heterogeneous conditions at room temperature with excellent yields.

A combination of trichloroisocyanuric acid and sodium nitrite in the presence of wet SiO 2 was used as an effective nitrosating agent for the nitrosation of N,N-dialkyl amines to their corresponding nitroso derivatives under mild and heterogeneous conditions in moderate to excellent yields.

A combination of inorganic chloride salts [e.g. WCl6, AlCl3 and ZnCl2] and sodium nitrite in the presence of wet SiO2 were used as an effective nitrosating agent for the nitrosation of secondary amines to their corresponding nitroso derivatives under mild and heterogeneous conditions in moderate to excellent yields.
