INTRAMOLECULAR [4+2] DIELS-ALDER CYCLOADDITIONS OF 2-SUBSTITUTED PHOSPHABENZENE AND ARSABENZENE IN TRIOSMIUM CLUSTERS
(Amer. Chem. Soc., 1994-09)
2-(Trimethylsilyl)-1-phosphabenzene and -1-arsabenzene, Me(3)SiC(5)H(4)E (E = P, AS), react with [Os3H2(CO)(10)] to give the clusters [Os3H2(Me(3)SiC(5)H(4)E)(CO)(9)], which contain sigma-bonded, four-electron-donating mu ...
Correlating experimental electrochemistry and theoretical calculations in 2 '-hydroxy chalcones: the role of the intramolecular hydrogen bond
(Royal Soc Chemistry, 2015)
In this work we present a study on the molecular structure and electrochemical behavior of a
series of methoxylated 2'-hydroxychalcones, whose antitumor activity has been previously
described. Cyclic voltammetry was used ...
Theoretical and infrared studies on the conformations of monofluorophenols
(Elsevier Science BvAmsterdamHolanda, 2012)
Experimental and computational study of 6-exo and 7-endo cyclization of Aryl radicals followed by Tandem SRN1 substitution
(American Chemical Society, 2013-04)
The reaction of N-allyl-N-(2-halobenzyl)-acetamides and derivatives was investigated in liquid ammonia under irradiation with the nucleophiles Me3Sn−, Ph2P− and O2NCH2 −. Following this procedure, novel substituted 2- ...
New insights into frustrated Lewis pairs: structural investigations of intramolecular phosphane-borane adducts by using modern solid-state NMR techniques and DFT calculations
(American Chemical Society - ACSWashington, DC, 2012-03)
Covalent bonding interactions between the Lewis acid and Lewis base functionalities have been probed in a series of “frustrated Lewis pairs” (FLPs) (mainly substituted vinylene linked intramolecular phosphane–borane adducts), ...
Synthesis of carbazoles by intramolecular arylation of diarylamide anions
(American Chemical Society, 2009-12)
The synthesis of a series of substituted 9H-carbazoles by the photostimulated SRN1 substitution reactionwith diarylamines as starting substrate was performed. The diarylamines were obtained by two approaches,the Pd-catalyzed ...
Aromatic nucleophilic substitution in aprotic solvents using hydrogen-bonded biological amines; kinetics studies and quantum chemical calculations
(Wiley, 2015-12)
Intermolecular and intramolecular non-bonding interactions play a crucial role in determining physical and biological properties of relevant amines, and we have recently reported that they are also responsible for changing ...
Evaluation of the catalytic specificity, biochemical properties, and milk clotting abilities of an aspartic peptidase from Rhizomucor miehei
(Springer, 2016-08-01)
In this study, we detail the specificity of an aspartic peptidase from Rhizomucor miehei and evaluate the effects of this peptidase on clotting milk using the peptide sequence of k-casein (Abz-LSFMAIQ-EDDnp) and milk powder. ...
1,3-Diaxial steric effects and intramolecular hydrogen bonding in the conformational equilibria of new cis-1,3-di substituted cyclohexanes using low temperature NMR spectra and theoretical calculations
