Arynes meet aldehydes in an alternating copolymerization! Our latest work is now out in @J_A_C_S, demonstrating a new chain-growth route to poly(o-arylene)-based polymers. Congratulations to everyone involved! pubs.acs.org/jacsat/article-…

Alternating Copolymerization of Arynes and Aldehydes Enabled by an N-Arylamine Initiator

Abstract. Here, we report the direct alternating copolymerization of arynes and aldehydes initiated by a simple N-arylamine. The N-arylamine framework is c

From photoexcited Ga(III) to Ga(I). Unexpectedly, Ga(I) reacts via photoinduced disproportionation, enabling the first oxidative addition of aryl iodides at a Group 13 center. Our latest work is now out in @J_A_C_S! Huge credit to Nijito and Sota! pubs.acs.org/doi/10.1021/jac…
