When Pb(CH3)4 was conducted with a stream of H2 over Ra, methyl exchange with recoil products was observed [69]. [Pg.148]

WO3 is turned grey-green by traces of Pb(CH3)4 contained in a stream of hydrogen. Heating in air does not remove the color. The reaction was proposed for qualitative analysis of Pb(CH3)4 [2]. Pb(CH3)4 was reported not to react with permanganate [4], but it should be considered that a 0.025% solution of KMn04 heated to 45 to 60°C has been employed for decontamination of Pb(C2H5)4 in transport containers [37]. [Pg.149]

Reaction of Pb(CH3)4 with AgN03 in alcoholic solution at room temperature gives metallic Ag and ethane in a 2 1 mole ratio, and the cation [Pb(CH3)3]+ [10]. When the metathesis was [Pg.149]

Pt(CH3)2 C8H8N2 (C8H8N2 = bipy. Formula II) is methylated by Pb(CH3)4 to give Pt(CH3)4 C8H8N2 after separation of elemental lead [99]. Pb(CH3)4 does not react with solutions of calcium hydridoiron carbonyl [20]. [Pg.150]

The redistribution reaction is quantitative in each case [6]. The compositions of mixtures obtained from redistribution of Pb(CH3)4 and Pb(C2H5)4 [7, 8, 12], of Pb(CH3)4 and Pb(C3H7)4 [Pg.151]

Refluxing a solution of Pb(C2H5)4 and p-tolylllthium for 8 h in benzene-ether affords di-p-tolyl [14], Only 0.9% ethyl group exchange, aside from much decomposition, had occurred between Pb(C2H5)4 and C-labeled NaC2H5 at room temperature after 2.5 months [67]. [Pg.178]

AlClg are carried out in CqHq [17]. Pb(C2H5)4 and AICI3 in a 1 4 mole ratio in CHCI3 react to give PbCl2 and presumably C2H5AICI2 [49]. [Pg.179]

Transethylation of tin(IV) and tin(ll) species by Pb(C2H5)4 occurs in abiotic and biotic systems at 20 °C. After 7 to 10 d incubation time in distilled water, Sn(C2H5)4 and [Sn(C2H5)3] are present. In a sediment system, under similar conditions, Sn(C2H5)4 is produced additionally, [SnC2H5] species form, but only from Sn compounds [165]. [Pg.179]

Reaction between Pb(C2H5)4 and [Pb(C2H5 3]+ to form [Pb2(C2H5)7] was observed by cyclotron resonance spectrometry using a total ion current single- and double-resonance technique [125]. [Pg.180]

Reactions of Pb(C2H5)4 with organolead compounds are discussed in the context of redistribution reactions (vide infra). [Pg.180]


CHR) , formed, e g. from the reaction of diazomethane and alcohols or hydroxylamine derivatives in the presence of boron compounds or with metal compounds. Poly-methylene is formally the same as polyethene and the properties of the various polymers depend upon the degree of polymerization and the stereochemistry. [Pg.320]

Threshold determinations for metal-containing compounds present a special case. If, for example, you process several different lead compounds, you would base your threshold determination on the total weight of all lead compounds processed. However, If you process both the parent" metal (lead) as well as one or more lead compounds, you must make threshold determinations for both because they are separately listed toxic chemicals. If you exceed thresholds for both the parent metal and compounds of that same metal, EPA allows you to file one combined report (e.g., one report for lead compounds, including lead) because the release Information you will report In connection with metal compounds will be the total pounds of the parent metal released. [Pg.30]

The factors in carboaromatic nucleophilic displacements summarized in this section are likely to be characteristic of heteroaromatic reactions and can be used to rationalize the behavior of azine derivatives. The effect of hydrogen bonding and of complexing with metal compounds in providing various degrees of electrophilic catalysis (cf. Section II, C) would be expected to be more extensive in heteroaromatics. [Pg.159]

Retard efficiently oxidation of polymers catalysed by metal impurities. Function by chelation. Effective metal deactivators are complexing agents which have the ability to co-ordinate the vacant orbitals of transition metal ions to their maximum co-ordination number and thus inhibit co-ordination of hydroperoxides to metal ions. Main use of stabilisation against metal-catalysed oxidation is in wire and cable applications where hydrocarbon materials are in contact with metallic compounds, e.g. copper. [Pg.782]

The solubility of most metals is much higher when they exist as organometallic complexes.4445 Naturally occurring chemicals that can partially complex with metal compounds and increase the solubility of the metal include aliphatic acids, aromatic acids, alcohols, aldehydes, ketones, amines, aromatic hydrocarbons, esters, ethers, and phenols. Several complexation processes, including chelation and hydration, can occur in the deep-well environment. [Pg.799]

In principle, molecular sieve carbons (MSC) can be achieved by the pyrolysis of thermosetting polymers such as polyvinylidene chloride, polyfurfuryl alcohol, cellulose, cellulose triacetate, polyacrylonitrile and phenol formaldehyde (Koresh 1980). An example is given by Trimm and Cooper (1970,1973) for the preparation of MSC (mixed with metallic compounds) for catalyst systems. A mixture of furfuryl alcohol, platinum oxide and formaldehyde was heated to 40°C and additional formaldehyde was added to ensure the... [Pg.49]
