Mechanochemical disulfide reduction reveals imprints of noncovalent sulfur⋯oxygen chalcogen bonds in protein-inspired mimics in aqueous solution
(Royal Society of Chemistry, 2020-11)
The surprisingly rich chemistry of mechanically activated cleavage of disulfide bonds has been uncovered only recently. Using a disulfide protein mimic together with Cleland's reagent (DTT) as the attacking nucleophile in ...
Mild and efficient one-pot synthesis of chiral beta-chalcogen amides via 2-oxazoline ring-opening reaction mediated by indium metal
(ELSEVIER SCIENCE SA, 2008)
A simple and efficient procedure for the synthesis of beta-seleno and beta-thio amides via the ring-opening reaction of chiral 2-oxazolines in the presence of indium metal has been developed. Features of this method include ...
An intramolecular 1,5-chalcogen bond on the conformational preference of carbonyl thiocarbamate species
(Royal Society of Chemistry, 2020-03-02)
Two closely related compounds, namely, O-methyl (4-fluorobenzoyl)carbamothioate (I) and O-methyl (4-methylbenzoyl)carbamothioate (II) were prepared in good yields by the reaction of the corresponding benzoyl isothiocyanates ...
Crystal packing of a zinc(II)-azide complex with a N,N,S-tridentate thiosemicarbazone ligand: An experimental and computational study
(2019-12-05)
The aim of this study was to provide a crystallographic and electronic analysis of a zinc(II)-azide complex with a N,N,S-tridentate thiosemicarbazone ligand. The characterization was performed by single-crystal X-ray ...
Enzymatic kinetic resolution of organochalcogenides in supercritical CO(2)
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
1-(Phenylthio)-, 1-(phenylseleno)- and 1-(phenyltelluro)-propan-2-ol were efficiently resolved by CAL-B in sc-CO(2). (C) 2011 Elsevier Ltd. All rights reserved.
Structures of Trichloromethyl Thiocyanate, CCl 3 SCN, in Gaseous and Crystalline State
(Wiley VCH Verlag, 2016-05)
Trichloromethyl thiocyanate, CCl3SCN, was structurally studied in both the gas and crystal phases by means of gas electron diffraction (GED) and single-crystal X-ray diffraction (XRD), respectively. Both experimental studies ...
Estudo da natureza de interações químicas do tipo calcogênio e halogênio mediante o estudo da estrutura eletrônica e da teoria quântica de átomos em moléculas
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2021-08-27)
In this work we present the results of a systematic analysis of the electronic structure of different chemical systems, through the Density Functional Theory (DFT), for the study of the nature of chemical bonds involving ...
Síntese e reatividade de N-alquinilindóis: preparação de N-alquinilindóis-2-substituídos e calcogenazolo[3,2-a]indóis
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2020-02-21)
This work reports the preparation of 2-Substituted-N-alkynylindoles 3 (18 examples) with yields that varied from 30 to 90%, via the metalation reaction of N-alkynylindoles 1 followed by the capture of 2-indolyl lithium ...
