Lithium organo- compounds reaction with

Organocadmium compounds can be prepared from Grignard reagents or organo-lithium compounds by reaction with Cd(II) salts.180 They can also be prepared directly from alkyl, benzyl, and aryl halides by reaction with highly reactive cadmium metal generated by reduction of Cd(II) salts.181... [Pg.661]

Sulfonium, cyclopropyldiphenyl tetrafluoroborate, 54, 28 Sulfonium salts, acetylenic, furans from, 53, 3 Sulfonium ylides, 54, 32 Sulfur, reaction with organo-lithium compounds, 50, 105 Sulfuryl chloride, with 1,1-cyclobutanedicarboxylic acid to give 3-chloro-l,1-cyclobutanedicarboxylic acid, 51, 73... [Pg.65]

Organocadmium compounds can be prepared from Grignard reagents or organo-lithium compounds by reaction with Cd(II) salts.136 Organocadmium compounds can also... [Pg.463]

Also other reaction types have been dealt with in CHEC(1984) and CHEC-II(19%) like reduction to alcohols (e.g., sodium borohydride), Wolff Kishner reduction, nucleophilic addition via reaction with Grignard reagents or organo-lithium compounds, and formation of imine type functional groups (e.g., hydrazones). New examples are the reaction of... [Pg.42]

Aminomethylotion. The reagent reacts with Grignard reagents to form N,N-bis(trimethylsilyl)amines in 60-90% yield (equation I). A similar reaction with organo-lithium compounds requires added magnesium biomide for satisfactory yields. ... [Pg.62]

Reaction with organo-lithium compounds works well with all three examples one molecule of formaldehyde is lost but a CH2OH group is retained in the products 56, 57, and 58 from addition of vinyl, phenyl, and butyl lithium. This chemistry was used to make bertyodionol.7... [Pg.312]

Lead salts of other inorganic and of organic acids may replace the lead chloride, as also may lead oxide or sulfide, and these may be brought into reaction with organo-lithium, -magnesium, -zinc, or -aluminum compounds methods for obtaining tetraethyllead have been studied in particular detail.465... [Pg.803]

Reactions of substituted prop-2-ynyl lithium compounds can similarly give acetylenic and allenic products. Huynh and Linstrumelle prepared the lithium acetylide 11 and confirmed its structure by NMR spectroscopy. Reaction with propylene oxide then gave a mixture of 12 (45%) and 13 (55%), showing that both organo-lithium species can react to give either allenic or acetylenic products. [Pg.489]

Anionic Polystyrene (PS), Styrene-Butadiene (SB), and Styrene-isoprene (SI) Copolymers Anionic addition polymerization requires monomers bearing carbon-carbon double bonds (C=C) able to form stable propagating carbanions (C-C ) after their formation through an electron transfer reaction with an organo-metal compound, most commonly n-butyl-lithium, X-butyl-lithium, and f-butyl-lithium initiators. The list of monomers meeting these conditions is relatively short, yet some commercially important addition monomers like styrene, butadiene, and isoprene are part of this list. [Pg.285]

Hoffmann and coworkers proposed an excellent method for evaluating the configurational stability of the lithium carbanion within the time scale of the rate of the reaction with an electrophile (Hoffmann test) [12]. The Hoffmann test is composed of two experiments. In the first experiment, a racemic organo-lithium compound is reacted with a racemic aldehyde such as 2-(Nd -diben-zylamino)-3-phenylpropanal,the relative rate of formation of the diastereomeric products (k55 kjjj) being estimated by an antUsyn ratio of the products (Fig. 5). [Pg.182]
