Palladium-catalyzed oxidative homocoupling and hydroxylation of 3-arylbenzo[d]isoxazoles was developed via direct C(sp²)-H bond activation using benzoisoxazoles as a new directing group. The protocols offered a divergent approach to functionalized, synthetically useful benzoisoxazoles in good yields. Critically, 1-iodo-4-methoxybenzene functioned as an oxidant to mediate the dehydrogenative homocoupling and minimize the cross-coupling. A dual-core dimeric palladacycle intermediate was confirmed by X-ray crystallog., and served as an active catalytic species in the catalytic cycles.

De Proft, F. published the artcileQuantum-Chemical Study of the Acidity of Substituted Acetic Acids with Density Functional Theory Based Descriptors, Product Details of C3H4F2O2, the publication is Journal of Physical Chemistry (1994), 98(20), 5227-33, database is CAplus.

Acidity differences of substituted acetic acids XCH₂COOH are interpreted in terms of the nature of the group X. Traditional quantum-chem. and d. functional theory based descriptors of chem. reactivity are calculated for 15 acids and are correlated with exptl. acidities in aqueous solution and in the gas phase. The results are interpreted within the framework of Pearson’s hard and soft acids and bases principle, stating that hard acids prefer to bond to hard bases and soft acids prefer to bond to soft bases. Calculated parameters, which are a measure of local hardness, show a pos. correlation with the exptl. acidities. The acidities in aqueous solution show almost no dependence on the softness (polarizability) of the group X, while this group softness seems to play an important role in the gas phase, although it is a minor one in comparison to the hard parameters.
