1,2-diborolanes with strong and without strong donor substituents have been described, and are also referred to as 1,2-diboracyclopentane. The 1,2-diaryl/alkyl-amino-1,2-diboracyclopentanes 2, 3, and 4 were obtained in good yield after the reaction of 1,2-dichloro-1,2-diboracyclopentane 1 with ArNHLi and Me₃Si-NR₂. The structures of these new derivatives were characterized by nuclear magnetic resonance spectroscopy. The molecular structures of 2b, 2c, 2e, 4, and 5f were also determined by single-crystal X-ray diffraction. The newly synthesized 1,2-borolanes are stable in air and showed particularly high activity against some Gram-positive bacteria.

已经描述了具有强供体取代基和不具有强供体取代基的1,2-二硼烷，并且也被称为1,2-二硼环戊烷。1,2-二芳基/烷基-氨基-1,2- diboracyclopentanes 2，3和4以良好的收率1,2-二氯-1,2-二diboracyclopentane的反应后获得1与ArNHLi和Me ₃ SI- NR ₂。这些新衍生物的结构通过核磁共振波谱表征。2b , 2c , 2e , 4 , 5f的分子结构还通过单晶 X 射线衍射测定。新合成的 1,2-硼烷在空气中稳定，对某些革兰氏阳性菌表现出特别高的活性。
