The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Silver(I) trifluoromethanesulfonate( cas:2923-28-6 ) is researched.SDS of cas: 2923-28-6.Ding, Yi; Sarkar, Samir Kumar; Nazish, Mohd; Muhammed, Shahila; Lueert, Daniel; Ruth, Paul Niklas; Legendre, Christina M.; Herbst-Irmer, Regine; Parameswaran, Pattiyil; Stalke, Dietmar; Yang, Zhi; Roesky, Herbert W. published the article 《Stabilization of Reactive Nitrene by Silylenes without Using a Reducing Metal》 about this compound( cas:2923-28-6 ) in Angewandte Chemie, International Edition. Keywords: bissilylene reaction silyl azide silver triflate; crystal structure nitrene silylene stabilized silaimine ring; mol structure nitrene silylene stabilized silaimine ring; amidinato ligands; hyperconjugative interactions; molecular orbitals; nitrene; silylenes. Let’s learn more about this compound (cas:2923-28-6).
Herein, the authors report the stabilization of nitrene reagents as the source of a N atom to synthesize N-incorporated R1LSi-N←SiLR2 (1; L = PhC(NtBu)2; R1 = NTMS2, R2 = NTMS). Compound 1 was synthesized by reacting bissilylene LSi(I)-Si(I)L with 3.1 equiv of Me3SiN3 at low temperature to afford a triene-like structural framework. Whereas the reaction of the LSi(I)-SiIL with 2.1 equiv of Me3SiN3 at room temperature produced silaimine 2 with a central four-membered Si2N2 ring which is accompanied by a silylene LSi and a cleaved silylene fragment. 1 Further reacts with AgOTf at room temperature to yield compound 3 which shows coordination of nitrene to Ag with the triflate salt. The compounds 1 and 2 were fully characterized by NMR, mass spectrometry, and x-ray crystallog. anal. The quantum mech. calculations reveal that compounds 1 and 2 have dicoordinated monovalent N atoms having two active lone pairs of electrons. These lone pairs are stabilized by hyperconjugative interactions.
