Propargyl ion
In organic chemistry, the propargyl group is a functional group of 2-propynyl with the structure CH≡C−CH2−. It is an alkyl group derived from propyne (HC≡C−CH3). The term propargylic refers to a saturated position (sp -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 alky… WebOct 24, 2024 · In this current work, propargyl methacrylate (PMA) was successfully adopted to be an efficient electrolyte additive to stabilize the formation of a solid electrolyte interface (SEI) layer on mesoporous carbon microbeads (MCMB) in Li-ion batteries, especially at elevated temperatures.

WebA gas-phase mechanism is studied to explain the production of propylene (C 3 H 6 ) in cold interstellar clouds. In this mechanism, propylene is formed by dissociative recombination of the precursor ion, ? ( ? ), with electrons. The protonated precursor ion is itself formed via two radiative association reactions involving ions and molecular hydrogen, starting with the …
