| A copper mediated coupling of alkynes with N-acylimines and N-acyliminium ions in water to generate propargyl amide derivatives was also reported. |
| Conjugate addition to enones and carbocupration of alkynes can also be achieved with organocopper compounds. |
| By careful use of appropriate conditions and catalysts alkanes can be converted into other hydrocarbons such as the alkenes and alkynes. |
| Alkanes have only single bonds, while alkenes have a carbon-carbon double bond, and alkynes have a carbon-carbon triple bond. |
