Phenylation - an overview ScienceDirect Topics
WebJan 1, 2001 · Phenylazotriphenylmethane and tetraphenylethane derivatives serve as thermal iniferters, and some organic sulfur compounds act as photoiniferters. Among the iniferters, several compounds containing N,N -diethyldithiocarbamyl groups were found to be excellent for the synthesis of polymers with well-controlled structures. WebThe thermal decomposition of phenylazotriphenylmethane in 3,5-dimethyl- and 3,4,5-trimethylisoxazole was studied. In 3, 5-dimethylisoxazole only the hydrogen atom of the methyl group in the 3 position is replaced by the (C 6 H 5) 3 C radical. The activities of the methyl groups of 3,4,5-trimethylisoxazole decrease in the order 3-C>4-C ≫ 5-C. health benefits of gastric bypass surgery
Reactions of allylpalladium(II) complexes with free radicals
WebAllylpalladium(II) compounds react readily in benzene with free phenyl and trityl radicals, generated from the thermal decomposition of phenylazotriphenylmethane, and with free cyclohexyl radicals, generated from the photolysis of (cyclohexyl)(pyridine)cobaloxime; the reactions appear to involve initial attack of the radicals at palladium, followed by … WebPolymer matrix particles useful for inhibiting scale formation in oil and gas wells are described. The insoluble, porous, crosslinked polymer matrix includes a polymer backbone and ionic functional groups covalently bonded to the backbone, the ionic functional groups being capable of selectively attracting and binding salt scale-forming ions when in contact … Webtion of phenylazotriphenylmethane in the presence of ferric chloride.
