A non-concerted single-electron transfer pathway has been established for the reductive elimination of 伪-iodo epoxides to allylic alcohols with sodium naphthalide; the exchange reaction between BuLi and RI must proceed exclusively by single-electron transfer to account for identity of rates of ...

Alternatively, Te powder (60 mesh) and sodium naphthalide (2 mol equiv) are stirred in THF for 4 h. Na2Te is isolated as an amber-coloured solid. The Na2Te (62.9 g, 0.362 mmol) is slurried in absolute EtOH (400 mL). The slurry is cooled at 0°C and allyl bromide (93.3 g, ...

When naphthalene is reduced in liq ammonia by metallic potassium, evaporation of excess ammonia gives the solvated solid potassium naphthalide (K2.NH3.Naphth2). If sodium is used in place of potassium, the product detonates as crystallization starts. This is attributed to energetic expulsion of ...
(62%). Resorcinol 132 was transformed into 134 via a four step sequences: methylation with NaH and MeI in dry DMF, reduction of the formyl group with NaBH4, mesylation of the resulting alcohol and subsequent reduction of the mesylate. The preparation of phthalide 135 was affected in ...
The preparation of phthalide 135 was affected in quantitative yield on treatment of 134 with K2CO3 in dry MeOH. Selective ozonolysis of compound 135, followed by Jones oxidation and esterification afforded ester 136. Demethylation with BCl3 in DCM followed by hydrolysis of the ester function gave...

Tris(triphenylphosphine)dinitrogen cobalt hydride (I) reacts with sodium naphthalidene (NaNp) to give a paramagnetic binuclear cobalt complex which is a catalyst for olefin hydrogenation; for example, the system (I)/NaNp 1/1 converts 20 moles of styrene into ethylbenzene under conditions where (...
