Résumé
Phenolic aerogels based on resorcinol-formaldehyde (RF) are among the best thermally insulating materials. However, the hydrophilicity inherent to the free phenolic moiety of RF gels generally limits their actual range of applications. Prior efforts to render phenolic gels hydrophobic are restricted to post-synthetic functionalizations of hydrophilic gels, processes that are often limited in efficiency, scope, and/or longevity. Here, an acid-mediated conversion of 1,3,5-trimethoxybenzene with formaldehyde is reported, yielding monolithic trimethoxybenzene-formaldehyde (TMBF) aerogels and xerogels with low density (0.11-0.30 g cm

A drastic example of such an anionic acceleration is provided by oxy‐Cope rearrangements which can be sped up by several orders of magnitude when deprotonated alcohols are used, D. A. Evans, A. M. Golob, J. Am. Chem. Soc. 1975, 97, 4765.

The sol‐gel polymerization of phloroglucinol and resorcinol with various aldehydes in non‐aqueous solvents had been patented, T. F. Baumann, J. H. Satcher, A. E. Gash, The Regents of the University of California, US7291653B2, 2004, Surprisingly, also the applicability of their base‐mediated protocol to alkylated resorcinol and phloroglucinol derivatives is claimed in the patent. We were, however, unable to reproduce the synthetic protocols reported therein for ethers.

A lack of equilibrium can be ruled out since increasing the respective equilibrium times in a control experiment did not alter the resulting isotherms (Figure S22a, Supporting Information).
