WebbExcept where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Ethylmagnesium bromide is a Grignard reagent with formula C 2 H 5 MgBr. It is widely used in the laboratory synthesis of organic compounds . WebbThis synthesis application is described in the following equations. The first two equations show how acetylene can be converted to propyne; the last two equations present a synthesis of 2-pentyne from propyne. H-C≡C-H + NaNH 2 (in ammonia or ether) → H-C≡C-Na (sodium acetylide) + NH 3. H-C≡C-Na + CH 3 -I → H-C≡C- CH 3 + Na I.
