From the seeds of Leucaena glauca B, obtained from the Netherlands Indies, we isolated leucaenine which, under the name leucaenol, was first described in 1937 by Mascre, who determined for this compound the empirical formula C4H5O2N. We obtained abou

This paper describes an investigation into the kinetics of the autoxidation of xanthene to xanthylium ion and hydrogen peroxide in a perchloric acid/acetic acid mixture at 20°. Apart from acid catalysis, the reaction also shows the characteristics o

Thermal decarboxylation of sodium trichloroacetate in 1,2-dimethoxyethane yields NaCl, CO2, CO, CCl4, perchloroisopropenyl acetate (I) and perchloro-1,2-dimethylenecyclobutane (II). Strong evidence is presented for the intermediate formation of trich

2-Cyano-2-propyl radicals (R) generated by decomposition of 2,2′-azo-isobutyronitrile were found to add on to anthracene (A) at one of the reactive 9,10 positions, yielding radicals R—A with a free valence at the other meso-position. The latter c

In the autoxidation of cumenes to benzoic acids at about 140° in butyric acid as solvent and with Co- and Mn-acetates as catalysts the main side-reaction is the formation of dimethylbenzyl alcohols. It may be suppressed by employing a low hydrocarbo

It has been shown by NMR spectroscopy that protonation of formic acid in HF-BF3 solution leads to an equilibrium mixture of two different proton adducts, which probably differ in the configuration around the partly double carbon-oxygen bond. Diffusio

The oxidation with oxygen of p-substituted isopropylbenzenes in butyric acid solution at 130-150° to the corresponding benzoic acids has been investigated, using manganese and cobalt acetates as catalysts. This reaction is slow compared with the oxi

A survey is given of the possible reactions between alkanes and protons or carbonium ions and in addition new kinetic data for some of these electrophilic aliphatic substitutions, including the hydrogen-deuterium exchange in mono-deuteroethane, and t

The reaction of thiols (R'SH) with 2-cyano-2-propyl radicals (R), generated by thermal decomposition of 2,2′-azoisobutyronitrile (RN = NR), was investigated. The radicals (R) readily abstract a hydrogen atom from the thiol (R'SH), producing isobuty
