Dimethylamine also can be nitrosated photochemically in aqueous solutions containing nitrite with the reaction occurring most readily at alkaline pH (Ohta et al 1982). 2.11 Physical Properties Clear, colorless liquid or gas with a strong, ammonia-like odor. Odor threshold concentrations of33 ppbv ...
The reaction can be performed under very mild conditions (30–50 °C), in a theoretically 100 % carbon‐economical fashion, with water as the only by‐product. The reaction was successfully applied to non‐activated linear 1‐alkenes, thus opening an access to industrially relevan...
