摘要：

Aromatic with boron: Two-electron heteroaromatic compounds 1 and 2 undergo oxidations and reactions with electrophiles (reducing the number of framework electrons by two and four, respectively) under conservation of aromaticity. In contrast, corresponding reactions of the known dianion 3, a six-electron aromatic four-membered ring, lead to loss of aromaticity (R = SiMe3).
