Methylidenecarbene (systematically named λ2-ethene and dihydrido-1κ2H-dicarbon(C—C)) is an organic compound with the chemical formula C=CH2 (also written [CCH2] or C2H2). It is a metastable proton tautomer of acetylene, which only persists as an adduct. It is a colourless gas that phosphoresces in the far-infrared range. It is the simplest unsaturated carbene. (en) Le méthylidènecarbène (systématiquement nommé λ 2 -éthène et dihydrido-1κ 2 H -dicarbone( C — C ) ) est un composé organique de formule chimique C=CH2 (aussi écrit [CCH2] ou C2H2). C'est un tautomère de proton métastable de l'acétylène, qui ne persiste que sous forme d'adduit. C'est un gaz incolore phosphorescent dans l'infrarouge lointain. C'est le carbène insaturé le plus simple. (fr) |
