Reactions with Lithium

In contrast to the reaction with lithium amide, the sodium amide suspension immediately settles out after stopping the stirring and the supernatant ammonia has a grey or black colour, due to colloidal iron. In some cases it took a long time before all of the sodium had been converted (note 4). A further 0.1 g of iron(III) nitrate was then added to accelerate the reaction and some liquid ammonia was introduced to compensate for the losses due to evaporation. [Pg.20]

Apparatus 4-1 flask (see Fig. 2) for the reaction with lithium amide 3-1 silvered Dewar flask, provided with a rubber stopper and a gas outlet for the hydroxyalkylation (no stirring was applied). [Pg.64]

The use of CIF and BrF as ionizing solvents has been studied (102,103). At 100°C and elevated pressures, significant yields of KCIF [19195-69-8] CsClF [15321-04-7], RbClF [15321-10-5], I-CBrF [32312-224], RbBrF [32312-224], and CsBrF [26222-924]obtained. Chlorine trifluoride showed no reaction with lithium fluoride or sodium fluoride. [Pg.186]

Additional uses iaclude (/) filling the enclosed space ia double-pane wiadow units to reduce noise and heat transmission (87,88) (2) acting as a source of power from the reaction with lithium to produce heat (89,90) and (J) pressurizing recreation ball packages such as tennis balls to give improved shelfhfe (91). [Pg.243]

Reduction. Coumarin is reduced to o-hydroxycinnamyl alcohol by reaction with lithium aluminum hydride (21). By reaction with diborane coumarin gives o-aUylphenol [1745-81 -9] (22). [Pg.320]

Propargylic alcohols are reduced by reaction with lithium aluminum hydride and subsequent hydrolysis to ( J-allylic alcohols via an organoaluminum intermediate (A) as shown below ... [Pg.146]

Ai -A-homo-4-ketones by reaction with lithium and biphenyl at The resulting dienone is transformed into the corresponding tropone by treatment with bromine. The Swiss chemists also found that base treatment of 19-mesyloxy-A " -3-oximes gives directly 4-oximino-A-homo-estra-l(10),2,4a-trienes in moderate yield. ... [Pg.369]

The determination of position of protonation by reaction with diazomethane was performed as follows The enamine was treated at —70° with ethereal hydrogen chloride and the suspension of precipitated salt was treated with diazomethane and allowed to warm slowly to —40°, at which temperature nitrogen was liberated. The reaction with lithium aluminum hydride (LAH) was carried out similarly except that an ether solution of LAH was added in place of diazomethane. The results from reaction of diazomethane and LAH 16) are summarized in Table 1. [Pg.172]

The chiral naphthyloxazoline substrates can also be employed in asymmetric carbon-heteroatom bond-forming reactions with lithium amides, which provide unusual... [Pg.243]

Intramolecular cyclization of 2-phenysulfonylmethyl lactam 3 took place upon reaction with lithium hexamethyldisilazan via generating its a-sulfonyl carbanion to give a cyclized postulated intermediate that can be quenched with trimethylchlorosilane to afford the stable silyl ketal 4. The later ketal was desulfonylated by Raney-Ni and desilylated through treatment with tetrabutyl ammonium fluoride (BU4NF) to afford the carbacephem 5 (94M71) (Scheme 1). [Pg.73]

A ketone vvith a substituent group in its /3 position might be prepared by a conjugate addition of that group to an a,/3-unsaturated ketone. In the present instance, the target molecule has a propyl substituent on the /3 carbon and might therefore be prepared from 2-methyl-2-cyclopentenoneby reaction with lithium dipropylcopper. [Pg.729]

Recently, optically active (+)-(R)-methy 1 tolyl sulfoxide 102, R = H was alkylated with a very high diastereoselectivity136. The sulfoxide was treated with either lithium diisopropy-lamide (LDA) or lithium tetramethylpiperidide (LTMP) to form the lithio-derivative, which upon subsequent reaction with lithium a-bromomethyl acrylate gave a mixture of two diastereomers of a-methylene-y-sulfinylcarboxylic acid 103. The use of the sterically highly hindered base, LTMP, gave the product with a higher diastereoselectivity. For example, the Sc4 Rc4 ratio was 95 5 when R was the methyl group. [Pg.609]

Nucleophilic addition to acetylenic sulfoxides provides a,/ -ethylenic sulfoxides. Treatment of 181 with monoalkyl-copper afforded nearly quantitatively /J-alkylated a, / -ethylenic sulfoxides 182 through cis-addition to the triple bond. The reaction with lithium dimethylcuprate also afforded a similar adduct however, the reaction with lithium di-n-butylcuprate was found to give a small amount of ethyl n-butyl sulfoxide 183 besides the... [Pg.620]

Sodium and potassium nitrates give an explosive reaction with lithium. [Pg.167]

Chromium (III) oxide gave rise to a very violent reaction with lithium heated to 180 C. The temperature exceeds 1000 C. It is a typical thermite reaction during which a more electropositive metai violentiy reduces an oxide by forming a metal, which is chromium in this particular case. However, the mixture needs to reach a high temperature to be able to react. [Pg.200]

There are also useful procedures for preparation of azides directly from alcohols. Reaction of alcohols with 2-fluoro-l-methylpyridinium iodide followed by reaction with lithium azide gives good yields of alkyl azides.75... [Pg.232]

Benzyne can also be generated from o-dihaloaromatics. Reaction with lithium amalgam or magnesium results in the formation of transient organometallic compounds that decompose with elimination of lithium halide. o-Fluorobromobenzene is the usual starting material in this procedure.126... [Pg.1039]
