Propargyl group
Appearance
In organic chemistry, propargyl is an alkyl functional group of 2-propynyl with the structure HC≡C−CH2−, derived from the alkyne propyne.
The term propargylic refers to a saturated position (sp3-hybridized) on a molecular framework next to an alkynyl group;
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 moiety;
- a 3-butynyl fragment, HCC-CH2CH2-, or substituted homologue.
