ALKYLATION NON CONVENTIONNELLE DE FRIEDEL ET CRAFTS DES AROMATIQUES PAR LES ISO ET CYCLOALCANES INDUITE PAR LES CHLORURES-SELECTIVITE ET OPTIMISATION

Friedel-Crafts alkylation of benzene by C5-C8 isoalkanes induced by tert-butyl chloride affords good yields in the presence of small amounts of AlCl3.The isomeric alkylbenzenes prepared by hydride transfer are similar to those obtained by direct alkylation from the corresponding equivalent alcohols and chlorides.The kinetic tertiary alkyl benzene rearranges to a more stable secondary isomer ; the formation of isomers discussed.Fragmentation of isoalkanes (when any) is very small except with isooctane which gives only a tert-butyl-cation.The reaction may be extended to toluene, chlorobenzene and dichlorobenzene with no major change in selectivity i.e. trans vs direct alkylation.An optimization of the reaction using dichlorobenzene increases significantly conversion and selectivity in trans-alkylation product and stresses the importance of low temperature (ca. 40 deg C) and small amounts of catalyst.
