A superbase is a compound that has a particularly high affinity for protons. Superbases are of theoretical interest and potentially valuable in organic synthesis . [ 1 ] [ 2 ] Superbases have been described and used since the 1850s.
According to calculations, ortho-diethynylbenzene dianion is the strongest superbase and has a proton affinity of 1,843.987 kJ/mol (440.723 kcal/mol). [1] The meta isomer is the second-strongest, and the para isomer is the third. All three are readily able to accept any proton to its ethynyl tails, from almost any compound.
Ortho-diethynylbenzene dianion (C 6 H 4 (C 2) 2) 2− (the strongest superbase ever synthesized) Meta-diethynylbenzene dianion (C 6 H 4 (C 2) 2) 2− (second strongest superbase) Para-diethynylbenzene dianion (C 6 H 4 (C 2) 2) 2− (third strongest superbase) Lithium monoxide anion (LiO −) was considered the strongest superbase before ...

In chemistry, the Verkade base (or Verkade superbase) is a powerful superbase with the formula P(MeNCH 2 CH 2) 3 N. A colorless oil, it is an aminophosphine although its inventor John Verkade called it proazaphosphatrane. The trimethyl derivative or 2,5,8,9-tetraaza-1-phosphabicyclo[3.3.3]undecane is the simplest.
