* Organometallic compounds: These compounds contain a metal atom directly bonded to a carbon atom. While they may contain hydrogen, they are not strictly limited to carbon and hydrogen. For example, organolithium compounds (like methyllithium) are commonly used in organic synthesis.
* Organophosphorus compounds: These compounds contain phosphorus atoms bonded to carbon atoms. Some examples include:
* Phosphines: Containing a phosphorus atom with three carbon bonds, like triphenylphosphine.
* Phosphonates: Containing a phosphorus atom with a double bond to an oxygen atom and two single bonds to carbon atoms.
* Organosilicon compounds: These compounds contain silicon atoms bonded to carbon atoms. Examples include:
* Silanes: Containing silicon atoms with hydrogen atoms attached.
* Siloxanes: Containing silicon atoms linked by oxygen atoms.
* Organohalogen compounds: These compounds contain a halogen atom (like chlorine, bromine, or iodine) bonded to a carbon atom. While they often contain hydrogen, they don't have to.
* Organic nitrogen compounds: While nitrogen is commonly found in organic compounds with carbon and hydrogen, some nitrogen-containing compounds lack carbon and hydrogen. Examples include:
* Amides: Containing a nitrogen atom bonded to a carbonyl group, like formamide.
* Amines: Containing a nitrogen atom bonded to one or more carbon atoms, like methylamine.
It's important to note that the definition of "organic compound" is not always clear-cut and can vary depending on the context.
