Reduction of dicarbapentaboranes(5) to 1,2-diborata-4-boracyclopendienes: Antiaromatic compouds with 4π-electron systems
Unverzagt,Winkler,Brock,Hofman,Von Rague Schleyer,Massa,Berndt
, p. 853 - 855 (2007/10/03)
Instead of tetragonal pyramids like 1, the antiaromatic 1,2-diborata-4-boracyclopentadiene five-membered rings 3 are formed on two-electron reduction of dicarbapentaboranes(5) 2.
