Chemistry – A European Journal, Volume 31, Issue 65, November 20, 2025.A quinonoidal dipyrrolyldiketone boron complex with an orthogonally arranged catechol unit in the dianionic form exhibited diradical properties, as observed from the singlet–triplet energy gaps (ΔEST) that were modulated by coexisting countercations. ΔEST values were controlled by the bridging boron moieties in the dianion diradicals.

Diels-Alder reactions of 3-furylamines in organic and aqueous solvents [PDF]
, 2006 Various 5-methyl-3-aminofurans have been shown to undergo facile Diels-Alder reactions with methyl acrylate in aqueous media. Reactions proceeded with exclusive regiochemistry, and enamine cycloadducts were readily hydrolyzed to afford 7-oxabicyclo[2.2.1]
