Reaction kinetics and catalyst deactivation during the redn. of NO with CO on a 0.5%Pt-3.4%MoO3/a-Al2O3 catalyst were investigated. The reaction shows an ignition/quenching behavior. After ignition, the reaction kinetics (formation of N2 and N2O) obey the ...
There are not so many fluorine, trifluoromethyl and trifluoromethoxy contg. arenes and heterocycles that are com. available and inexpensive. To exploit this bonanza optimally, one should be able to introduce addnl. substituents, in particular functional gr ...
As a rule, tri-, tetra- and pentahaloarenes readily undergo ortho-lithiation when treated with amide-type bases. However, halogen migration occurs whenever the substrate contains three or more contiguous halogen atoms, provided that at least one of them is ...
Indenyllithium reacts with dichlorobis(dimethylamino)diborane(4) with formation of bis(dimethylamino)bis(1-indenyl)-diborane(4) which rearranges on heating to the isomer bis(dimethylamino)bis(3-indenyl)diborane(4). The mixed isomer bis(dimethylamino)(1-ind ...

The stability and water exchange dynamics of gadolinium (GdIII) complexes are critical characteristics that determine their effectiveness as contrast agents for magnetic resonance imaging (MRI). A new heteropodal GdIII chelate, [Gd-TREN-bis(6-Me-HOPO)-(TAM ...
For the low-spin t2g6 Ru(OH2)62+ (ΔV⧧ = −0.4 cm3 mol-1) and Rh(OH2)63+ (ΔV⧧ = −4.2 cm3 mol-1) hexaaquaions, the respective Id and Ia water exchange mechanisms had been assigned, mainly on the basis of activation volumes ΔV⧧ and entering ligands effects for ...
An efficient synthesis of cycloisodityrosine was developed based on an intramol. nucleophilic arom. substitution reaction for the selective ring formation of a key biaryl ether intermediate. Cycloetherification of dipeptide I gave exclusively the (meta,par ...
A review with 62 refs. The appropriate choice of a metalating reagent is the key to the optional deprotonation of benzylamine derivs. at a position adjacent to the substituent or the nitrogen bearing side chain or even at the benzylic a-position of the lat ...
The 2-fluoroalkyl esters, e.g. FCH2CH2CO2Me are readily accessible by the base-catalyzed acylation of fluorohydrines. A two-step procedure is required to prep. the 1-fluoroalkyl esters: conversion of alk-1-enyl carboxylates ("ene esters") into the 2-brom ...
