propyne
Propyne (methylacetylene) is an alkyne with the chemical formula . It is a component of MAPD gas—along with its isomer propadiene (allene), which was commonly used in gas welding. Unlike acetylene, propyne can be safely condensed.Peter Pä ...
().
The term propargylic refers to a
saturated position (
''sp''3-hybridized) on a molecular framework next to an
alkynyl group. The name comes from mix of ''propene'' and ''argentum'', which refers to the typical reaction of the terminal alkynes with
silver salts.
The term homopropargylic designates in the same manner
* a saturated position on a molecular framework next to a propargylic group and thus two bonds from an
alkyne
