The Schmidt reaction is the reaction of hydrazoic acid or an alkyl azide with a carbonyl compound, alkene, or alcohol, often in the presence of a Brønsted or Lewis acid. Although the family of Schmidt reactions includes a number of variants, they all result in the migration of a substituent from carbon to nitrogen with loss of a molecule of dinitrogen.
An environmentally benign, copper-catalyzed diazidation of a broad range of olefins, including vinylarenes, unactivated alkenes, allene, and dienes, under mild conditions with TMSN 3 (trimethylazidosilane) as azido source, has been developed. A rapid and efficient method has been developed for the synthesis of vicinal bromoazide directly from olefin using N-bromosuccinimide (NBS) and trimethylsilyl azide (TMSN 3) as the bromine and azide sources, respectively, without any catalyst in acetonitrile as solvent.The rate of reaction is remarkably fast in acetonitrile without catalyst to produce bromoazides in high yield. An asymmetric ring-opening reaction of meso-aziridines with TMSN3 was developed using a catalyst prepared from Y(OiPr)3 and chiral ligand 2 in a 1:2 ratio. Excellent enantioselectivity was realized from a wide range of substrates with a practical catalyst loading. The products were efficiently converted to enantiomerically enriched 1,2-diamines, which are versatile chiral building blocks for ChemicalBook あなたのためにトリメチルシリルアジド(4648-54-8)の化学的性質を提供して、融点、価格、蒸気圧、沸点、毒性、比重、沸点、密度、分子式、分子量、物理的な性質、毒性 税関のコードなどの情報、同時にあなたは更にトリメチルシリルアジド(4648-54-8)の製品の全世界の供給商にブラウズ The Schmidt reaction is the reaction of hydrazoic acid or an alkyl azide with a carbonyl compound, alkene, or alcohol, often in the presence of a Brønsted or Lewis acid.

The azide-alkyne Huisgen cycloaddition is a 1,3-dipolar cycloaddition between an azide and a terminal or internal alkyne to give a 1,2,3-triazole. Rolf Huisgen was the first to understand the scope of this organic reaction.American chemist Karl Barry Sharpless has referred to this cycloaddition as "the cream of the crop" of click chemistry and "the premier example of a click reaction." Treatments of various nitriles with TMSN 3 and Bu 2 Sn(OAc) 2 at 30 °C in benzene for 60 h yielded the corresponding 5-substituted 1H-tetrazoles in good to excellent yields.This method is a mild and efficient alternative reagent system for Wittenberger tetrazole-synthesis that uses TMSN 3 and Bu 2 SnO in toluene at high temperature (93–110 °C) for 24–72 h.

Thus, the condensation of various alkenes with TMSN3 and Selectfluor in aqueous CH3CN at RT led to the efficient and regioselective synthesis of β-fluorinated alkyl azides with excellent TMSN3 also results in formation of a robust solid electrolyte interphase (SEI), consisting of a composite of lithium nitride, reduced nitrates, and siloxanes that appears to limit both Li dendrite A facile synthetic method for the formation of dihydroquinoline-azide from alkylidenecyclopropanes and TMSN3 under the catalysis of a Lewis acid has been developed, and a number of azide-containing compounds can be instantly accessed in moderate to good yields. A click reaction with these azido compounds was A convenient and efficient manganese‐catalyzed trifluoromethylazidation of alkenes has been developed by utilizing inexpensive and readily available CF 3 SO 2 Na under mild conditions. The various β‐trifluoromethylated alkyl azides were directly obtained from corresponding allyl, vinyl, chain terminal and internal alkenes, and easily further transformed into other CF 3 ‐containing Anti Dihydroxylation. Epoxides may be cleaved by aqueous acid to give glycols that are often diastereomeric with those prepared by the syn-hydroxylation reaction described above. Proton transfer from the acid catalyst generates the conjugate acid of the epoxide, which is attacked by nucleophiles such as water in the same way that the cyclic bromonium ion described above undergoes reaction.
