The positional and structural izomerization equilibrium of branched pentylbenzenes

The equilibrium of the positional and structural isomerization of branched monopentylbenzenes, pentyltoluenes, and pentyl-o-xylenes was studied. It was found that the 1,2-dimethylpropyl substituted derivatives prevail over the 1,1-dimethylpropyl substituted isomers in the equilibrium mixture of all of the examined groups of compounds. The thermodynamic characteristics of the structural isomerization of pentylbenzenes were calculated from the experimental data.

Synthesis of new 7-benzofuranmethanamines as heterocyclic analogues of the squalenepoxidase-inhibitor Butenafine

Selected title compounds (6a-f, 7a-d) were synthesized by RedAl(R)-reduction of the carboxamides 4a-f and 5a-d, easily available from the corresponding (2,3-dihydro-)7-benzofurancarboxylic acids 1a-f or 2a-d, respectively. For practical reasons, the preparation of the 2,3-dihydro-2-methyl-7-benzofuranmethanamines 6h-k with varied N-substitution by alkylation of the N-methyl-benzofuranmethanamine 6g with preformed aralkylbromides 9a-d was preferred.

Theoretical and Spectroscopical Investigations of Indigo Dyes, XXII. - Preparations of 5,5'- and 6,6'-Dialkylated Indigo Dyes

The manifolded applicabilities of indigo dyes are strongly restricted by the low solubility of most of their representatives.We describe in this paper the preparation of a series of dialkylated indigos 1, thioindigos 2, dyes of the cibaviolett-type 3, and of the corresponding vinylogues 4, 5, and 6 by different synthetic methods.Some of the prepared compounds show a remarkable solubility and can be used for spectroscopic measurements even in non-polar solvents.
