Irradiation of p-methoxyazidobutyrophenone (1) in methanol yielded 2-(4-methoxyphenyl)-1-pyrroline (2) and several other photoproducts. However, the presence tris(trimethylsilyl)silane (TTMSS), 2 is formed selectively. Transient absorption ESR spectroscopy verify that irradiation 1 forms triplet alkylnitrene 31N through intramolecular energy transfer from ketone (T1K). DFT calculations indicate abstracts H atoms TTMSS but not methanol, which explains selectivity. Thus, alkylnitrenes can...
Excited-state intramolecular hydrogen transfer on the triplet surface of salicylideneaniline derivatives has received much less attention than corresponding ultrafast process singlet surface. To enhance understanding this reactivity, photochemical properties a series salicylidene-α-hydroxy acid salts with different substituents phenol moiety (1-3) were characterized. UV/vis absorption and phosphorescence measurements in ethanol revealed that 1-3 exist as both enol keto tautomers, form being...
Abstract Sunlight‐driven photochemical reactions are an important tool for sustainable organic synthesis. However, compared with ground states, which the effects of structure on properties and reactivity well established, understanding excited states is limited. In particular, improved aromaticity antiaromaticity in necessary to develop strategic methods synthesizing polycyclic aromatic compounds. Herein, using density functional theory (DFT)‐optimized structures, singlet (S 0 ) lowest...
Although nitrene chemistry is promising for the light-induced modification of organic compounds, reactivity large polycyclic aromatic compounds and effects their curvature remain unexplored. Irradiation azidocorannulene (
The processes of the sublimation and thermal decomposition 1‐ethyl‐3‐methylimidazolium hexafluorophosphate ionic liquid (EMImPF6) were studied by a complex approach including Knudsen effusion mass spectrometry, IR NMR spectroscopy, quantum chemical calculations. It was established that vapor over phase primarily consists products under equilibrium conditions. Otherwise, neutral ion pairs are only components Langmuir To identify nature an experiment on distillation performed collected...

Spiropyrans are heterocyclic organic compounds known for their photochromic properties which of perspective use technology. They can be potentially used as the elements molecular machines, optical data recording, modulated light filters and numerous hybrid materials. The key characteristic such is an ability to enter a reaction, taking place upon irradiation with UV (see Figures 1 2). To develop more possibly practical most important problem investigate chemical both theoretically...
Triplet arylnitrenes may provide direct access to aryl azo-dimers, which have broad commercial applicability. Herein, the photolysis of p-azidostilbene (1) in argon-saturated methanol yielded stilbene azo-dimer (2) through dimerization triplet p-nitrenostilbene (3 1N). The formation 3 1N was verified by electron paramagnetic resonance spectroscopy and absorption (λmax ~ 375 nm) cryogenic 2-methyltetrahydrofuran matrices. At ambient temperature, laser flash 1 formed 370 nm, 2.85 × 107 s-1 )....
