The temperature required to induce cross-linking in typical benzocyclobutene-based thermosets is near 250 °C, which exceeds the use temperature of many chemical components. A new and versatile synthesis of BCB-functionalized monomers has allowed access to monomers that can be incorporated into a variety of macromolecular platforms to enable significantly reduced cure temperatures. Incorporation of BCB-functionalized comonomers in polystyrene and polynorbornene enabled insolublization of thin films by curing at only 120 °C for 1 h.

Although transition-metal-catalyzed C-C bond activation has been investigated extensively, C-C bond cleavage manipulated by hydrogen transfer has been unexplored. In this work, we disclose a skeleton reorganization of alkene-tethered benzocyclobutenols through Rh-catalyzed C-C bond cleavage coupled with intra- and intermolecular hydrogen transfer. The reaction pathway was well-tuned by the catalytic systems. As a result, divergent benzofurans bearing 4-β-hydroxy or 4-β-keto moieties were synthesized under pH- and redox-neutral conditions.
