Malononitrile (133) undergoes Pd(0)-catalyzed dimerization to give 134[125,126]. The trimerization of malononitrile in boiling benzene catalyzed by potassium tetrakis(pentalluorophenyl)palladate gives 4.6-diamino-3,5-dicyano-2-cyanomethylpyridine (135)[127]. [Pg.544]

Tetrakis-Cp uranium complexes are readily prepared via metathesis of UCl and KCp in refluxing benzene. These complexes are a relatively rare example of a pseudotetrahedral complex with four Tj -Cp rings, (rj-ring) (25). The Cp derivative has been shown to react with CO and CO2 to give acyl and carboxylato complexes. This complex also reacts with alkyl haUdes to afford the U(IV) complex, Cp UX (X = halide). [Pg.334]

Amtnonolysis of tetrakis(l,2,3,5-trifluoromethyl)benzene with liquid ammonia in a sealed tube gives a tncyano derivative [99] (equation 85). [Pg.468]

The reaction of 1,2,4,5-tetrafluorobenzene in NVV -dimethylimidazolidin-l-one (DMT) with sodium or alkaline methyl mercaptide gives l,2,4,5-tetrakis(methyl-thio)benzene [26] (equadon 16). [Pg.505]

A synthetically useful virtue of enol triflates is that they are amenable to palladium-catalyzed carbon-carbon bond-forming reactions under mild conditions. When a solution of enol triflate 21 and tetrakis(triphenylphosphine)palladium(o) in benzene is treated with a mixture of terminal alkyne 17, n-propylamine, and cuprous iodide,17 intermediate 22 is formed in 76-84% yield. Although a partial hydrogenation of the alkyne in 22 could conceivably secure the formation of the cis C1-C2 olefin, a chemoselective hydrobora-tion/protonation sequence was found to be a much more reliable and suitable alternative. Thus, sequential hydroboration of the alkyne 22 with dicyclohexylborane, protonolysis, oxidative workup, and hydrolysis of the oxabicyclo[2.2.2]octyl ester protecting group gives dienic carboxylic acid 15 in a yield of 86% from 22.

Benzene reacted with excess 3 in the presence of aluminum chloride at room temperature for 4 h to give peralkylated product," hexakis[2-(methyldichloro-sily I )ethyljbenzcne (4a) and other alkylated products pentakisl2-(mcthyldichloro-silyl)ethyl]benzenc (4b), tetrakis 2-(methyldichlorosilyl)ethyljbenzene (4c), tris 2-(methyldichlorosilyl)ethyl]benzene(4cl), and bis 2-(methyldichlorosilyl)ethylJ-benzene (4e) (Eq. (6)). The product distributions were plotted against mole ratios of 3/benzene in Fig. I. [Pg.159]

Coordination studies of acyclic thioether ligands to silver(I) centers has also been studied. Poly(alkylthio)aromatic systems have been used to form supramolecular silver(I) compounds. With the ligand 2,3,5,6-tetrakis(isopropylthio)benzoquinone the compound has a linear chain structure in which silver(I) has a tetrahedral coordination.1156 A similar structure has the compound with the hexakis(methylthio)benzene,1157 but with the hexakis(tolylthio)benzene the silver...

Benzenetricarbonyl trichloride and l,2,4,5-tetrakis(bromomethyl) benzene were employed as multifunctional initiators for the synthesis of 3-and 4-arm PTHF stars, respectively [147]. The living ends were reacted with sodium 2-bromoisobutyrate followed by reduction with Sml2. The samarium enolates, thus formed were efficient initiators for the polymerization of MMA to give the (PTHF-fo-PMMA) , n = 3 or 4 star-block copolymers, according to Scheme 71. [Pg.84]
