Propynyyliryhmä

Propynyyliryhmä is the Finnish term for the propargyl group, an organic functional group with the structure -CH2C≡CH. It is derived from propyne by the removal of a hydrogen atom from the methyl group. The propargyl group is characterized by the presence of a triple bond adjacent to a methylene group. This structural feature makes the propargyl group highly reactive. It can participate in a variety of chemical reactions, including nucleophilic substitution, addition reactions across the triple bond, and cycloaddition reactions. The propargyl group is often encountered in organic synthesis as a protecting group for alcohols or amines, or as a building block for more complex molecules. It is also found in some natural products and pharmaceuticals. The nomenclature "propargyl" originates from the Spanish word "propargo," meaning "to drive forward," referring to the driving force of the triple bond in chemical reactions.
