ortho-Carborane is the organoboron compound with the formula C 2 B 10 H 12. The prefix ortho is derived from ortho. It is the most prominent carborane. This derivative has been considered for a wide range of applications from heat-resistant polymers to medical applications. It is a colorless solid that melts, without decomposition, at 320 °C
In contrast, smaller carboranes are usually prepared by building-up routes, e.g. from pentaborane + alkyne, etc. For example ortho-carborane can be degraded to give [C 2 B 9 H 12] −, [9] which can be manipulated with oxidants, protonation, and thermolysis. [C 2 B 9 H 12] − + Fe 3+ → C 2 B 8 H 12 + "B +" + Fe 2+ [C 2 B 9 H 12] − + H ...
Organoboron. Organoboron chemistry or organoborane chemistry studies organoboron compounds, also called organoboranes.These chemical compounds combine boron and carbon; typically, they are organic derivatives of borane (BH 3), as in the trialkyl boranes.
In organoboron chemistry, a carboryne is an unstable derivative of ortho-carborane with the formula B 10 C 2 H 10. [1] They are also called 1,2-dehydro-o-carboranes. The hydrogen atoms on the C2 unit in the parent o-carborane are missing. The compound resembles and is isolobal with benzyne.

Carborane acids H(CXB 11 Y 5 Z 6) (X, Y, Z = H, Alk, F, Cl, Br, CF 3) are a class of superacids, [1] some of which are estimated to be at least one million times stronger than 100% pure sulfuric acid in terms of their Hammett acidity function values (H 0 ≤ –18) and possess computed pK a values well below –20, establishing them as some of the strongest known Brønsted acids.
