Design and characterization of pH-sensitive spirorhodamine 6G probes with aliphatic substituents
(Elsevier Science SA, 2019-11)
We report synthesis and photophysical studies of spirorhodamines (SRA) with amide N-aliphatic substituents, including measurements of single-crystal X-ray structures, fluorescence emission, and quantum mechanical calculations. ...
Substituent effects on the photolysis of methyl 2-carboxylate substituted aliphatic 2H-azirines
(Elsevier Science, 2007-05)
In this study, the UV induced photochemical reactions of two 2H-azirines – methyl 2-chloro-3-methyl-2H-azirine-2-carboxylate (MCMAC) and methyl 3-methyl-2H-azirine-2-carboxylate (MMAC) – isolated in argon matrices are ...
Relative influence of noncovalent interactions on the melting points of a homologous series of 1,2-dibromo- 4,5-dialkoxybenzenes
(Wiley Blackwell Publishing, Inc, 2013-01)
Crystal structures are presented for two members of the homologous series of 1,2-dibromo-4,5-dialkoxybenzenes, viz. those with decyloxy and hexadecyloxy substituents, namely 1,2-dibromo-4,5-bis(decyloxy)benzene, C26H44Br2O2, ...
Methyl 3-methyl-2H-azirine-2-carboxylate photochemistry studied by matrix-isolation FTIR and DFT calculations
(American Chemical Society, 2006-08)
The aliphatic 2H-azirine, methyl 3-methyl-2H-azirine-2-carboxylate (MMAC), has been synthesized and its monomeric form investigated by IR spectroscopy in an argon matrix, at 10 K, as well as theoretically (DFT/B3LYP/6-31 ...
Synthesis of arylselenide ethers by photoinduced reactions of selenobenzamide, selenourea and selenocyanate anions with aryl halides
(Pergamon-Elsevier Science Ltd, 2011-03)
Selenobenzamide (-SeCNH(Ph), 1), selenourea ( -SeCNH(NH2), 2) and selenocyanate (-SeCN, 3) anions afford areneselenolate ions (ArSe-) under photostimulation in the presence of tert-butoxide or 2-naphthoxide ions as electron ...
Unusual Photochemical C-N Bond Cleavage in the Novel Methyl 2-Chloro-3-methyl-2H-azirine-2-carboxylate
(American Chemical Society, 2006-07)
The structure, preferred conformers, vibrational spectrum, and photochemical behavior of the novel azirine, methyl 2-chloro-3-methyl-2H-azirine-2-carboxylate (MCMAC) were investigated in low-temperature matrixes and in the ...
New one-pot synthesis of anti-tuberculosis compounds inspired on isoniazid
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2020-12)
A library of thirty N-substituted tosyl N’-acryl-hydrazones was prepared with p-toluenesulfonyl hydrazide, methyl propiolate and different aldehydes in a one-pot synthesis via an aza-Michael reaction. The scope of the ...
