Naoc2h5 reagent

WitrynaCoroglaucigenin, which is known to be a 3β, 14β, 19-trihydroxy-5α-card-20: 22-enolid, was transformed into 2α, 3β, 19-triacetoxy-14β-hydroxy-5α-card-20 : 22-enolid. The latter was identical with the known tri-O-acetyl-19-dihydro-calotropagenin. The structure of calotropagenin (1) is thus established through an independent way. WitrynaThus, even though sodium amide (NaNH 2) is an exceptional base (pK a of NH 3 ~ 33), in water it is only as good as sodium hydroxide. On the other hand, NaNH 2 is a far more basic reagent in ammonia than is NaOH. The pH range allowed by a particular solvent is called the acid-base discrimination window.

WitrynaThe key difference between the S N 2 and E2 reactions is that the nucleophile in the S N 2 mechanism attacks the carbon connected to the leaving group (ɑ-carbon) while in E2, the base attacks one of the β-hydrogens. The result is a replacement of the leaving group with a nucleophile, in the S N 2, and a newly-formed π bond in the E2 reaction.
