| 1-Hexyne Usage And Synthesis |
Chemical Properties | colourless liquid | Uses | 1-Hexyne is used in the preparation of tricyclic isoindolinone scaffold by undergoing hydrozirconation and ring-closing metathesis. It is used to prepare trans-1,2-bis(5-thianthreniumyl)alkene tetrafluoroborate by reacting with thianthrene cation radical tetrafluoroborate. | Definition | ChEBI: 1-hexyne is a terminal acetylenic compound that is hexane carrying a triple bond at position 1. It is a terminal acetylenic compound, an alkyne and a volatile organic compound. | General Description | 1-Hexyne reacted with thianthrene cation radical tetrafluoroborate to form trans-1,2-bis(5-thianthreniumyl)alkene tetrafluoroborate. | Hazard | Probably flammable. | Purification Methods | Distil it from NaBH4 to remove peroxides. Stand over sodium for 24hours, then fractionally distil it under reduced pressure. Also dry it by repeated vacuum transfer into freshly activated 4A molecular sieves, followed by vacuum transfer onto Na/K alloy and stirring for 1hour before fractionally distilling.
