'''다이보레인'''(diborane, 디보란)은 B<sub>2</sub>H<sub>6</sub> 화학식을 갖는, [[붕소]]와 [[수소]]로 이루어진 [[화합물]]이다. 실내 온도에서는 달콤한 향의 무색의 기체이다. 다이보레인은 공기와 잘 섞이기 때문에 폭발 혼합물을 만들기 쉽다. 다이보레인은 실내 온도에서 습기가 찬 공기에 닿으면 자연 발화한다. 삼중심 이전자 결합을 한다.

== 합성 ==

== 역사 ==
다이보레인은 19세기 금속 붕소화물을 가수분해하면서 처음 합성하였으나, 이에 대해 분석되지는 않았다. 1912년부터 1936년까지 [[앨프리드 스톡]]은 연구를 통해 [[에테인]]과 같은 구조의 다이보레인을 처음 제안하였다.<ref>{{서적 인용 |author= Stock A.|year = 1933|제목 = The Hydrides of Boron and Silicon| edition = |publisher = Cornell University Press|location = New York| id = | page= }}</ref> S.
