Thermal Degradation of Polymers and Polymer Models.IV. Thermolysis of a Polymethacrylate Model with an Unsaturated End Group
Morrow, Gregory R.,Rae, Ian D.
, p. 1477 - 1481 (1987)
Thermal Degradation of a model for the 'unsaturated end group' of poly(methyl methacrylate) gives products which suggest that homolytic bond cleavage, and not a retro-ene reaction, is the major pathway.The diester (CH3)2C(COOCH3)CH2C(COOCH3)=CH2, when heated at 250/300 deg, gives up to 50 mole percent of methyl 2-methylpropanoate (methyl isobutyrate).

The synthesis of cyclodextrin-centred star polymers via thiol-ene addition of per-6-thio-β-cyclodextrin (CD-(SH)7) with vinyl terminated polymers is described. The obtained thiol-ene product was employed as an initiator for ring opening polymerization (ROP) of ε-caprolactone (ε-CL).

scheme or table, p. 3690 - 3693 (2010/12/20)
Ru(η6-naphthalene)(η4-1,5-COD) (1) (10 mol %) catalyzes the tail-to-tail dimerization of methyl methacrylate (MMA) in MeCN in 74% yield at 70 °C for 4 h. Without use of solvent complex 1 (1 mol %) rapidly catalyzes the tail-to-tail dimerization and trimerization of MMA in 59% and 23% yields, respectively, at 70 °C for 5 min.
Thermal Cross-coupled Dimerisation of Alkali and Alkaline Earth Metal Salts of Methacrylic-Crotonic Acid Binary Systems in the Solid State
Kudoh, Masaaki,Naruchi, Kiyoshi,Akutsu, Fumihiko,Miura, Masatoshi
, p. 105 - 106 (2007/10/02)
Thermal reaction of sodium and potassium salts of methacrylic-crotonic acids in the solid state selectively affords a cross-coupled dimer, dimethyl hex-1-ene-2,4-dicarboxylate.
On the Catalytic Dimerization of Acrylic Acid Derivatives by Palladium Complexes. IV. The Dimerization of Methyl Methacrylate
Oehme, G.
, p. 779 - 790 (2007/10/02)
Methyl methacrylate has been dimerized to a mixture of 2.5-di(methoxycarbonyl)-hex-1-ene (1) and (E)-2.5-di(methoxycarbonyl)-hex-2-ene (2) by catalytic systems containing dichlorobis (nitrile)-palladium(II) and silver tetrafluoroborate.Codimerization experiments with methyl acrylate show a lower reactivity of methyl methacrylate.Oxidative addition of β-chloro methyl methacrylate to tetrakis(triphenylphosphine)palladium(0) gave β-palladio methyl methacrylates (8,9) suitable for model investigations of the catalytic reaction.A proposal is given for a mechanism via Pd(IV) intermediates.
