A carbene is a molecule that has a neutral carbon atom with a valence of two and two unshared valence electrons. They are neutral transitory carbon intermediates. They have two valence electrons that are not shared, as well as a neutral carbon atom with a valency of two. They are denoted as R-(C:)-R’, or R2<\/sub>C: R denotes the substituent group or hydrogen atoms. They can be singlets or triplets depending on their structure.<\/p>\n\n\n

Carbenes are uncharged, electron-deficient chemical entities that consist of a divalent carbon atom surrounded by a sextet of electrons and two substituents.<\/p>\n\n\n\n

The simplest carbene is the CH2<\/sub> compound, which is known as methylene and was initially used in the nineteenth century. Dumas first described his attempts to prepare the parent carbene (CH2<\/sub>) through the dehydration of methanol in 1835.<\/p>\n\n\n\n
