The solution is administered after dilution by the intravenous route as an electrolyte replenisher. identify the alkyne (and hence the acetylide ion) and the alkyl halide needed to synthesize a given alkyne. 8 9 The reagent may be formed in liquid ammonia, which serves to …
Sodium acetylide (Na(C2H)) Ethynyl sodium. Sodium amide (strong base pKa = 38) R C C Na NH3 Equilibrium favors the weaker side, forming the acetylide ion nucleophile R C C CH 3CH2 Br R C C CH2CH Br Sn2 The carbon nucleophile reacts with the sp3 carbon of the electrophile and displaces the leaving group. The high stability of the acetylide anion makes metal acetylides relatively poor nucleophiles. CHLORATE-TRIMERCURY- ACETYLIDE PREPARATION: Chemicals: acetylene /calcium carbide + water/ mercuric nitrate sodium chlorate Materials: glass beaker 300 ml acetylene generator (see above) MANUFACTURE: 1 .

sodium ethynide. Packaging 100, 500 g in Sure/Seal™ Terminal alkynes can also form salts with certain heavy-metal cations, notably silver (I) and copper (I). % slurry in xylene: light mineral oil, 95% (Purity of contained acetylide) Sigma-Aldrich pricing. The properties of alkynes pretty much follow the same pattern of those of alkanes and alkenes. Sodium Acetylide in Xylenes. determine whether or not the reaction of an acetylide ion with a given alkyl halide will result in substitution or elimination, and draw the structure of the product formed in either case. Lithium acetylides are readily prepared by deprotonation of acetylenes using a variety of organmetallic bases to form Li (BuLi), Mg (iPrMgCl), Zn (NR 3, Zn(OTf)) or other metal acetylides.
