Styrene allylic

Aryl and vinylic bromides and iodides react with the least substituted and most electrophilic carbon atoms of activated olefins, e.g., styrenes, allylic alcohols, a,p-unsaturated esters and nitriles.

The diplatinum complexes [Pt(jU-H)SiR3(PCy3)]2 catalyze the addition of silanes R3SiH (R = Me, Et, PhCH2) Ph, OEt, Cl) to pentene-1, hexene-1, styrene, allyl chloride and 2-methylpropene. The relative reactivity order in silane is given, and the catalyst substrate ratio is 10-4-10-6 1. The majority of the reactions are carried out at ambient temperature and are exothermic. Dienes are also hydrosilylated.223 The complexes also catalyze the hydrosilylation of butyne-1, phenylacetylene, butyne-2 and diphenylacetylene in 70-90% yield. The...

The equilibria present between olefins such as styrene, allylic esters, or 3,3-dimethyl butene-1 and palladium(II) acetate in acetic acid, have recently been studied 212). In the rate of acetate concentrations in which the acetate-bridged dimer [Na2Pd2(OAc)e] is the main species (Section II, A, 2), some peculiar results were observed. When olefin was added to the solution, a rapid change in spectra occurred followed by a slower change. The fast equilibrium is... 

Early studies of the supported metal complexes utilized as hydrosilylation catalysts focused on the immobilization of H2PtCl6 on ion exchangers. Chloroplatinic acid and other Pt complexes have been used as efficient precursors of the catalysts anchored to silica or organic materials for the hydrosilylation of 1-alkenes, styrene, allyl derivatives, and acetylene [2, 84-87].

The Wacker reaction has also been applied to numerous simple alkenes such a-alkenes or cycloalkenes, or to functionalized alkenes such nitroethylene, acrylonitrile, styrene, allyl alcohol, or maleic acid [3]. The carbonyl group is formed at the carbon atom of the double bond where the nucleophile would add in a Markovni-kov addition (Eq. 5). Among these different alkenes, the oxidation of propene to acetone is the only oxidation which has been developed to an industrial scale. 

Degradation in the presence of solvents has also been applied to the conversion of other styrenic polymers, such as poly(p-methylstyrene) and poly(styrene-allyl alcohol).64,65 Figure 4.11 shows the temperature dependence of the conversion of poly(p-methylstyrene) when using phenol, 1-methyl-naphthalene and tetralin as solvents. In this case, tetralin leads to the greatest degradation below 370 °C, whereas the order is reversed above that temperature. These results indicate that the effect of the solvent in the degradation of styrenic polymers is strongly influenced by the temperature.

A detailed discussion of the earlier work on this can be found in CHEC-I. The cycloaddition of tetrachlorothiophene-1,1-dioxide with azulene takes place in the [4 + 2]mode rather than a [4 + 6]mode. A frontier orbital-based explanation has been provided for this <85TL2607). 2-Menthyl-3,4,5-trihalothiophene-1,1-dioxides have been found to be asymmetric diene equivalents <88T3I27>. Dienophiles such as styrene, allyl alcohol and acrylamide lead to regio- and stereoisomerically pure adducts, which then eliminate SO2 to form dihydrobenzene derivatives.
