The chemistry of the alpha , omega -diphenylalkanes, C//6H//5(CH//2)//nC//6H//5 left bracket n equals 1-4 right bracket , in highly purified anhydrous SbCl//3 and SbCl//3-10 mol % AlCl//3 melts has been investigated from 100 to 130 degree C by in situ **1H NMR spectroscopy and by quench and separation techniques. These substrates, which are often used to model the aliphatic chains that link aromatic and hydroaromatic clusters in coal, are found to undergo selective cleavage of the sp**2-sp**3 bond. For n equals 1 and 2 products are formed via a transaralyklation reaction, while for n equals 3 and 4 the cleavage results in the selective production of only benzene and either indan (n equals 3) or tetralin (n equals 4). Toluene is also reactive in SbCl//3-AlCl//3, and typical transalkylation chemistry is observed.

The electrophilic organofluorophosphonium catalyst [(C6F5)3PF][B(C6F5)4] is shown to effect benzylation or alkylation by aryl and alkyl CF3 groups with subsequent hydrodefluorination, thus resulting in a net transformation of CF3 into CH2-aryl fragments. In the case of alkyl CF3 groups, Friedel-Crafts alkylation by the difluorocarbocation proceeded without cation rearrangement, in contrast to the corresponding reactions of alkyl monofluorides.
AsCat and FurCat: New Pd catalysts for selective roomerature Stille cross-couplings of benzyl chlorides with organostannanes

Two novel succinimide-based palladium complexes, AsCat and FurCat, are highly efficient catalysts for roomerature Stille cross-coupling of organostannanes with benzyl chlorides. The air- and moisture-stable catalysts are prepared in one step, and the coupling reactions proceed with a high selectivity for the benzyl position under mild conditions without the need for additives.
