Experimental and GIAO 15N NMR study of substituent effects in 1 H -tetrazoles
(American Chemical Society, 2012-04)
A series of 1-aryl/alkyl-1H-1,2,3,4-tetrazoles, 5-substituted 1H-tetrazoles, and 1,5- and 2,5-disubstituted 1H-tetrazoles were studied by a combination of experimental NMR (natural abundance 15N, 15N/ 1H HMBC, and 13C) and ...
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. ...
The effects of substituents and solvents on the conformation of benzophenones
(BioChem Press, 2004-06)
Motivation. Natural and synthetic benzophenones are compounds of great scientific and applied interest due to the varied biological and physicochemical properties that they posses. As part of a program aimed at investigating ...
