Thermolysis of manganese(III) acetate in acetic anhydride and in acetic anhydride/acetic acid mixtures
Autor: W. J. De Klein
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 96:22-25
The thermolysis of manganese(III) acetate in acetic anhydride/acetic acid mixtures has been studied. In acetic anhydride succinic anhydride is the main reaction product with acetoxyacetic acid the main side product. In acetic acid the reverse situati

Copper(II)-catalyzed formation of decenoic acids from manganese(III) acetate and 1-octene in acetic anhydride/acetic acid mixtures
Autor: W. J. De Klein
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 94:151-153
The reaction of 1-octene with manganese(III) acetate in acetic anhydride/acetic acid mixtures in the presence of Cu(II) salts gives 4-decenoic acid as a major product, together with some 3-decenoic acid. The 4-decenoic acid, after esterification, is

Telomer Acids: Monocarboxylic acids with long-chain branching; Their derivatives, properties and potential uses in lubricants
Autor: W. J. De Klein, H. Van Brederode
Publikováno v: Journal of the American Oil Chemists' Society. 61:247-254
Telomer acids are synthesized by addition of acetic anhydride to α-olefins using managenese (III) acetate as a free radical initiator. The telomerization mechanism comprises initiation, propagation and termination steps. The reaction product consist

Infrared spectra and structure of N-halogen secondary amides
Autor: W. J. de Klein, A.R. Plesman
Publikováno v: Spectrochimica Acta Part A: Molecular Spectroscopy. 28:673-686
N-Cl, N-Br and N-J secondary amides have been investigated in the i.r. From the data on N-H and CO stretching vibrations in carbon tetrachloride solution it appears that the N-halogen aliphatic amides show cis-trans isomerism across the C-N amide

Infrared-spectroscopic identification of compounds separated by gas-liquid chromatography, using a potassium bromide micropellet technique
Autor: W. J. de Klein
Publikováno v: Fresenius' Zeitschrift für analytische Chemie. 246:294-297
A combination of gas-chromatography and infrared spectroscopy is described. Samples down to a few micrograms are collected from the gas-chromatograph by a cold trap technique. The collected material is transferred to potassium bromide and is measured

Publikováno v: Spectrochimica Acta Part A: Molecular Spectroscopy. 27:93-102
The multiplets in the carbonyl region of the infrared spectrum of some disubstituted and monosubstituted malonic acids have been investigated. Examination of the acids in a range of solvents and solvent mixtures showed the presence of both open and i

Steric and solvent effects on the cis-trans equilibrium of secondary N-Cl amides—An infrared and 'H NMR spectroscopical investigation
Autor: W. J. de Klein
Publikováno v: Spectrochimica Acta Part A: Molecular Spectroscopy. 28:687-700
Steric and solvent effects on the cis-trans isomerism of secondary N-Cl amides are investigated. Infrared data of N-H and CO stretching vibrations in carbon tetrachloride show that the cis-trans equilibrium is highly dependent on the presence of b

Electrochemical synthesis of vicinal dithiocyanates from olefins and a thiocyanate salt in acidic media
Autor: W. J. De Klein
Publikováno v: Electrochimica Acta. 18:413-416
The addition of electrochemically generated thiocyanogen to olefins is described. The effect of solvent and irradiation is briefly outlined. In acidic media the reaction takes place without irradiation. In acetic acid thiocyanogen adds smoothly to th
