that Pd-catalyzed cross-coupling at sites of severe steric hindrance are disfavored, we herein show that the oxidative addition to C-Br ortho to an adamantyl group is as favored as the corresponding adamantyl-free system due to attractive dispersion forces. This enabled the development of a fully selectivearylation and alkylation of C-Br ortho to an adamantyl group, even if challenged with competing

A low dielectric constant material has a polymeric network that is fabricated from a first and a second component. The first component comprises a polymeric strand, and the second component comprises a molecule having a central portion with at least three arms extending from the central portion, wherein each of the arms includes a backbone with a reactive group. The first component and the second component form the polymeric network in a reaction that involves at least one of the reactive groups when the first and second components are thermally activated. Contemplated low dielectric constant materials are advantageously employed in the fabrication of electronic devices, and particularly contemplated devices include integrated circuits.
