“…Different synthetic procedures are usually used to prepare alkyl and aryl azides. The former ones can be obtained by nucleophilic aliphatic substitution, by heating the proper alkyl halide with sodium azide in DMSO or DMF. The latter ones are generally prepared by treatment of diazonium salts with an azide anion .…”

The nucleophilic aromatic substitution of some activated aryl or heteroaryl halides has been performed in ionic liquid solution, using the 1-butyl-3-methylimidazolium azide as a nucleophile. The reaction course was studied varying the structures of both substrates and ionic liquids. In particular, in the latter case, the reaction of 2-bromo-5-nitrothiophene was carried out in five different ionic liquids ([bmim][BF 4], [bmim][PF 6], [bmim][NTf 2], [bm 2im][NTf 2], and [bmpyrr][NTf 2]). Finally, for all the substrates considered, a comparison with data obtained in MeOH solution in the presence of NaN 3 was also performed. Data collected indicate that in some cases it is possible to obtain aromatic or heteroaromatic azide derivatives in satisfactory yield by means of a S NAr reaction using [bmim][N 3] as the nucleophile.

“…Thionyl chloride is a versatile reagent widely used by the chemical industry for the synthesis of carboxylic acid chlorides, with many advantages compared with other chlorinating reagents, including ease of isolation of SO 2 end product, ease of handling (miscible with nearly all organic solvents), and very high yield in chlorinated products [28] . However, for commodity chemical production as is the case here, it is unlikely to be adopted for commercial scale levels of production.…”

This study offers an updated bioeconomy perspective on biobased routes to high‐purity silicon and silica in the context of the societal, economic and environmental trends reshaping chemical processes. We summarize the main aspects of the green chemistry technologies capable of transforming current production methods. Coincidentally, we discuss selected industrial and economic aspects. Finally, we offer perspectives of how said technologies could/will reshape current chemical and energy production.
