In organic chemistry, a carbyne is a general term for any compound whose structure consists of an electrically neutral carbon atom connected by a single covalent bond and has three non-bonded electrons. The carbon atom has either one or three unpaired electrons, depending on its excitation state; making it a radical. The chemical formula can be written R−C· or R−C3· (also written as ⫶C−R), or just CH. Carbynes can be seen as derivatives of the simplest such compound, the methylidyne radical or unsubstituted carbyne H−C· or H−C3·, in which the functional group is a hydrogen atom.

  • Em química, carbino é um termo geral para qualquer composto cuja estrutura molecular inclua um átomo de carbono eletricamente neutro com três elétrons não ligantes, conectado a outro átomo por uma ligação simples. Um carbino, portanto, tem a fórmula geral R-C3•, onde: * R é qualquer grupo monovalente. * O sobrescrito 3• indica os três elétrons não ligados. Não deve-se confundir com carbono acetilênico linear (LAC), um polímero usualmente conhecido como carbino e reconhecido por sua dureza elevada, porém sem relação com esta mesma categoria de compostos.

  • 卡拜(英語:Carbyne)是拥有三个自由电子的电中性单价碳活性中间体HC及其衍生物(如EtO2C-C)的统称。卡拜可通过很多方法获得。它可以短寿命的活性中间体存在于气相中。 卡拜可以与金属离子结合形成 (如[WBr(CO)2(2,2'-bipy)C-Ar]和[WBr(CO)2(PPh3)2C-NR2])。这类化合物的一种合成方法是让W(CO)6与二异丙基氨基锂(LDA)反应产生[(iPr2N)(OLi)C=W(CO)5],然后再让其与或Br2-PPh3和三苯基膦反应。另一种合成方法是用路易斯酸处理甲氧基。 (zh)

  • En química, un carbino es una especie de carbono monovalente radical que contiene un átomo de carbono univalente eléctricamente neutro con tres electrones no enlazados.​ Es más fuerte y más rígido que cualquier otro material conocido. De hecho, el carbino es aproximadamente 2 veces más fuerte que el grafeno y nanotubos de carbono, que hasta ahora eran los materiales más fuertes. El carbino tiene una larga lista de propiedades inusuales y muy deseable que lo convierten en un material interesante para una amplia gama de aplicaciones.​ (es)
  • Carbino, in chimica organica è spesso un termine generale per ogni composto che ha una struttura molecolare che include un atomo di carbonio elettricamente neutro con 3 elettroni di valenza liberi, connesso da un legame covalente singolo. L'atomo di carbonio ha uno o tre elettroni non accoppiati, a seconda del suo stato di eccitazione; rendendolo un radicale o un triradicale. (it)
