Matrix and ab initio infrared spectra of thiourea and thiourea-d4

Vibrational Spectroscopy, 1998
Abstract The FTIR spectrum of thiourea and thiourea-d 4 isolated in argon and nitrogen matrices are presented for the first time and discussed in terms of normal modes predicted by ab initio calculations. Vibrational frequencies, IR intensities and isotopic shifts obtained from the density functional B3-LYP/6-31+G(2d,p) calculations show the most ...

Cinchonine and thiourea

Chemical Communications, 2013
In this viewpoint, we discuss the seminal work contributed by Dixon, who reported the first use of a bifunctional cinchona-derived thiourea organocatalyst for the enantioselective conjugate addition of malonate esters to nitroalkenes. Since then, this class of catalysts has been extensively utilized in a variety of fundamental transformations.

Thermodynamic Analysis of Decomposition of Thiourea and Thiourea Oxides

The Journal of Physical Chemistry B, 2005
Thiourea has exhibited extremely rich dynamical behavior when being oxidized either through a chemical approach or via an electrochemical method. In this study, thermodynamic properties of thiourea and its oxides are investigated by measuring their thermogravimetry (TG), differential thermogravimetry (DTG), and differential scanning calorimetry (DSC ...

Oxidation of thiourea and substituted thioureas: a review

Journal of Sulfur Chemistry, 2011
Thioureas, containing sulfur and nitrogen atoms, are susceptible to oxidation by a large number of oxidants giving rise to various products including ureas, sulfides, oxides of sulfur, and nitrogen. Some novel cyclized products were also obtained during oxidation.
