In 1998, Miyaura reported a Rh(acac)(CO)2/dppp-catalyzed addition of aryl or alkenylboronic acids to aldehydes in aqueous organic mixtures under an inert atmosphere (Eq. 8.85).216 The use of electron-rich tri(tm-butyl)phosphine as ligand was found to be beneficial for obtaining good yields of the corresponding aldehyde addition products.217... [Pg.263]

Poly[/i-(alkylamino)borazines] can be prepared through a multistep thermolysis process involving tris(monoalkylamino)boranes of the type B(NHR)3 (R = Me, Pr ). Heating these molecular precursors under reduced pressure or in an inert atmosphere... [Pg.122]

An unusual synthesis of a rhenium(VI) nitrido complex has been observed with the ligand reaction of the rhenium(V) precursor [ReNCl2(PPh3)2] with 2,4,6-tri-isopropylbenzenethiolate, tipt, which gave the green rhenium(VI) complex [ReN(tipt)4], when the reaction mixture was exposed to air, whereas the pale orange rhenium(V) compound [ReN(tipt)4] was obtained in an inert atmosphere. ... [Pg.285]

Equimolar amounts of 2-acrylamido-2-methyl-l-propanesufonic acid and freshly distilled tris[2-(2-methoxyethoxy)-ethyl]amine were mixed under an inert atmosphere and stirred for 8 hours at ambient temperature or until 2-acrylamido-2-methyl-l-propanesulfonic crystals dissolved. The monomer salt consisted of a slightly yellow viscous clear liquid. The salt monomer was used in the next step without further purification. [Pg.34]

Tris(trimethylsilyl)arsine is a colorless liquid which melts slightly below room temperature, and is stable at room temperature under an inert atmosphere or in a degassed, flame-sealed ampoule. The H NMR spectrum in C7Ds (reference 6 2.09) consists of a single resonance at 5 0.30 and the 13C NMR spectrum shows a single peak at 6 4.31. Solubility very soluble in benzene, toluene, pentane, THF, and diethyl ether. [Pg.156]

As mentioned in the introduction, hydroperoxides can be measured by recording the area under the CL curve in an inert atmosphere i.e. the total luminous intensity (TLI). Kron et al. found that when measuring CL in inert atmosphere together with peroxide concentration, as measured by iodome-try, for oxidised polypropylene, proportional relationships were obtained when the TLI was plotted versus peroxide concentration (see Fig. 3) [60]. In addition, changes in melting temperature and polydispersity index with aging time have also been found to correlate with changes in the TLI [59]. [Pg.158]

In the present study, [N-Alk-Pz](TCNQ)m and [N-Alk-Pz](MTCNQ)m salts have been synthesized, with Aik for CnH2n+i n = 1, 2,...5 m 1,2. Aldrich- KodxLCQ pyrazine was used without any additional purification, while TCNQ and MTCNQ were refined by vacuum zone sublimation. Iodide alkyls were synthesized by the reaction of corresponding alcohols with phosphate tri-iodide followed by a distillation in inert atmosphere. To obtain alkylpyrazinium iodides, the quatemization reaction was used ... [Pg.321]

Fhosphane tellurides are pale-yellow solids. Most of these compounds are very sensitive to oxygen and decompose with deposition of tellurium when heated. Some of the compounds are light-sensitive. Phosphane tellurides can be stored under an inert atmosphere at low temperatures. The X-ray structure1 of tri(f-butyl)phosphane telluride and the 31P- and 125Te-NMR spectra of trialkylphosphane tellurides1,2 were reported. [Pg.22]

Tris[dimcthylamino]phosphane Telluride4 A mixture of 2.0 g (15.7 mmol) of finely ground tellurium and 2.75 g (16.9 mmol) of tris[dimethylamino]phosphane is heated under an inert atmosphere at 150-160° for 2 h. The mixture is then cooled and the deposited crystals are washed with petroleum ether yield 3.1 g (66%) m.p. 85°. [Pg.23]

Tris[4-hydroxy-2-methylphenyl] Tellnronium Chloride2 A mixture of 4.0 g (37 mmol) of 3-methylphenol and 5.0 g (18 mmol) of tellurium tetrachloride in carbon tetrachloride is heated under reflux in an inert atmosphere for 30 h, and then allowed to cool. The mixture is filtered, the filter cake is washed thoroughly with carbon tetrachloride and benzene, the solid is extracted with acetone, and the residue is dissolved in methanol. The methanol solution is concentrated, the precipitate is collected, dissolved in methanol, and the product reprecipitated by the addition of acetone yield 2.2 g (25%) m.p. 188-192°. [Pg.678]

The complexes can also be prepared from other monomeric rhodium(I) complexes. Both the triphenylphosphine and the tri(/>-tolyl)phosphine complexes can be prepared by refluxing solutions of the appropriate [RhCl(PAr3)3] complex in an inert atmosphere (equation 23).68 70 Alternatively one ligand of an [RhXL3] complex can be oxidized (equation 24).87,88... [Pg.909]

A number of substituted benzenes, naphthalenes, indans, pyridmes, and indoles form arene(tricarbonyl)chromium complexes upon thermolysis under an inert atmosphere, usually in a high boiling ether, or by irradiation of the arenes in the presence of chromium hexacarbonyl. The complexes are relatively air-stable and can usually be stored for long periods in the absence of light. Somewhat milder conditions can be used by transfer of the chromium tricarbonyl group from preformed naphthalene(tricarbonyl)chromium, tris(L)tricarbonyl chromium (L = acetonitrile, ammonia, pyridine), or tricarbonyl( -l-methylpyrrole)chromium. Enan-tiomerically pure arene(tricarbonyl)chromium complexes having two different substituents, either ortho or meta can be prepared conveniently by classical resolution of racemic... [Pg.3235]
