合成了B，B-二亚甲基取代二硫杂环-1，2-二氢-1，2-二硼环，并对其性质和反应活性进行了研究。由于1，2-二氢-1，2-二硼环具有明显的缺电子和抗芳香性，该化合物在常温下1atm下均解双原子氢(H-2)气体，得到氢桥联的双(硼烷)。这一反应伴随着从深绿色到黄色的戏剧性颜色变化，此外还有开启的荧光反应。
B,B-Dimesityl-substituted dithieno-1,2-dihydro-1,2-diborin was synthesized and its properties and reactivity were studied. Owing to the noticeably electron-deficient and antiaromatic character of the 1,2-dihydro-1,2-diborin ring, this compound was found to homolytically cleave diatomic hydrogen (H-2) gas at ambient temperature under 1 atm to afford a hydrogen-bridged bis(borane). This reaction was accompanied by a dramatic color change from dark green to yellow in addition to a turn-on fluorescence response.
