Tetracarbonyl(>f -methyl acrylate)ruthenium is obtained as a colorless solid that is stable indefinitely at temperatures below —30° under argon. The complex is soluble in organic solvents but decomposes unless free methyl acrylate is added to the solvent. It appears that an equilibrium is established [eq. (1)], involving the complex, methyl acrylate, and the species [Ru(CO)4]. Excess free methyl acrylate shifts the equilibrium to the left, thereby preventing decomposition of the complex and facilitating the workup of the... [Pg.49]

According to the assignments, the following equations relate the fractions of methoxy proton resonance observed in the A-, B-and C-resonance areas (F, Fg and F ), methyl acrylate centered triad fractions (F, FgMM MMS SMS) the probability that an MS or SM placement is coisotactic . [Pg.291]

The 3-oxidotriazolopyridinium zwitterions 245 fail to react with DMAD unless magnesium bromide is present, when ring opening occurs (2000H(53 265) (Section IV.F). The thiol 268 adds methyl acrylate as expected the resulting ester is converted via the acid hydrazide, to an oxadiazole (89IJC(B)170). [Pg.49]

The susceptibility of the polymerization of a given monomer to autoacceleration seems to depend primarily on the size of the polymer molecules produced. The high propagation and low termination constants for methyl acrylate as compared to those for other common monomers lead to an unusually large average degree of polymerization (>10 ), and this fact alone seems to account for the incidence of the decrease in A f at very low conversions in this case. [Pg.128]

A half-metallocene iron iodide carbonyl complex Fe(Cp)I(CO)2 was found to induce the living radical polymerization of methyl acrylate and f-bulyl acrylate with an iodide initiator (CH3)2C(C02Et)I and Al(Oi- Pr)3 to provide controlled molecular weights and rather low molecular weight distributions (Mw/Mn < 1.2) [79]. The living character of the polymerization was further tested with the synthesis of the PMA-fc-PS and PtBuA-fi-PS block copolymers. The procedure efficiently provided the desired block copolymers, albeit with low molecular weights. [Pg.47]

Miktoarm stars of the A(BC)2 type, where A is PS, B is poly(f-bulyl acrylate) (PtBA), and C is PMMA [161] have been synthesized, by using the trifunctional initiator 2-phenyl-2-[(2,2,6,6-tetramethyl)-l-piperidinyloxy] ethyl 2,2-bis[methyl(2-bromopropionato)] propionate (NMP, ATRP) (Scheme 86). In the first step, a PS macroinitiator with dual < -bromo functionality was obtained by NMP of styrene in bulk at 125 °C. This precursor was subsequently used as the macroinitiator for the ATRP of ferf-bulyl acry-... [Pg.99]

Other 2-substituted cyclopropylideneacetates of type 3-X also entered this cycloaddition (Scheme 15) [19]. The endolexo selectivity is low but usually still higher than that of simple acrylic acid esters. The relative Diels-Alder reactivities of dienophiles 1-Me and 3-X as determined by competition experiments (Scheme 15) suggest a mechanism involving either diradicals or zwitterions as intermediates [19]. Surprisingly, the 2-fluoro derivative 3-F is less reactive than the parent compound 3-H. The 2-chloro and 2-bromo derivatives 1-Me and 3-Br have similar reactivities and cycloadd to furan (57) about 16 times faster than methyl acrylate. [Pg.164]

Miki and Hachiken reported a total synthesis of murrayaquinone A (107) using 4-benzyl-l-ferf-butyldimethylsiloxy-4fT-furo[3,4-f>]indole (854) as an indolo-2,3-quinodimethane equivalent for the Diels-Alder reaction with methyl acrylate (624). 4-Benzyl-3,4-dihydro-lfT-furo[3,4-f>]indol-l-one (853), the precursor for the 4H-furo[3,4-f>]indole (854), was prepared in five steps and 30% overall yield starting from dimethyl indole-2,3-dicarboxylate (851). Alkaline hydrolysis of 851 followed by N-benzylation of the dicarboxylic acid with benzyl bromide and sodium hydride in DMF, and treatment of the corresponding l-benzylindole-2,3-dicarboxylic acid with trifluoroacetic anhydride (TFAA) gave the anhydride 852. Reduction of 852 with sodium borohydride, followed by lactonization of the intermediate 2-hydroxy-methylindole-3-carboxylic acid with l-methyl-2-chloropyridinium iodide, led to the lactone 853. The lactone 853 was transformed to 4-benzyl-l-ferf-butyldimethylsiloxy-4H-furo[3,4- 7]indole 854 by a base-induced silylation. Without isolation, the... [Pg.258]

Photocycloadditions of naphthalene derivatives to alkcnes have been recently reviewed.60 Examples of such reactions are the photocycloaddition of naphthalene to 2,3-dihy-drofuran,61 of 4-methoxy-l-naphthonitrile to acrylonitrile62 and of 2-trimethylsiloxynaph-thalene to methyl acrylate.63 2-Naphthols undergo cycloaddition with ethene in the presence of aluminum trihalides only.64 Other bicyclic aromatic compounds, e.g. A-acylindoles65-67 and /V-methylphenanthrene-9,10-dicarboximide,68 have also been studied in detail. Irradiation of 5/f-dibenzo[u,i7]cyclohepten-5-one (21) and dimethyl 2-methylfumarate (22) in dioxane gives the cyclobutane adduct 23 in 73% yield.69... [Pg.153]

For attack of F on acrylic acid, first a hydrogen bonded complex is formed which then proceeds to the transition state and then to a stable carbanion. The methyl in the methacrylic acid reduces stabilization of the carbanion as predicted. Subsequent studies using ammonia as the nucleophile indicated that attack proceeded by a rate-determining intramolecular proton transfer from the nucleophile to the ligand, assisted by a discrete water molecule that acts as a catalyst17. They predicted that acrolein underwent 1,4-addition, acrylic acid either 1,2- or 1,4-addition and acrylonitrile 1,2-addition. [Pg.1110]

Methyl acrylate did not react with ketene aminals 240 (R = Me, Cl) in dioxane at ambient temperature, but reactions took place on refluxing for 20-48 hours to yield hexahydro-6/f-pyrido[l,2-a]pyrimidin-6-ones 250 (R = Me, Cl) (86H2247 89SC1801). Hexahydro-6//-pyrido[ 1,2-a]-pyrimidin-6-one 250 (R = OMe) was also prepared in the reaction of ketene aminal 240 (R = OMe) and ethyl 3-bromopropionate in refluxing acetonitrile for 48 hours (89SC1801). Hexahydro-67/-pyrido[l, 2-cj] pyrimidin-6-ones 250 (R = H, Me, Cl, OMe) were prepared in better yields (79-91%) when the reaction mixture of ketene aminal 240 (R = H, Me, Cl, OMe) and an excess of methyl acrylate was irradiated in anhydrous methanol by a 450-W medium-pressure mercury lamp under nitrogen at ambient temperature for 3-5 hours (93SC1039). [Pg.164]
