Page/Page column 32, (2016/05/24)
Segregated fluorinated esters are described that are useful as dielectric fluids in electrical devices and as heat transfer agents.
POSITIVE RESIST COMPOSITION AND PATTERNING PROCESS
-
, (2010/04/23)
A positive resist composition comprises (A) a resin component which becomes soluble in an alkaline developer under the action of an acid and (B) an acid generator. The resin (A) is a polymer comprising recurring units containing a non-leaving hydroxyl group represented by formula (1) wherein R1 is H, methyl or trifluoromethyl, X is a single bond or methylene, m is 1 or 2, and the hydroxyl group attaches to a secondary carbon atom. The composition is improved in resolution when processed by lithography.

experimental part, p. 2830 - 2836 (2010/11/02)
Aza-Michael adducts are obtained in very good yields by the conjugate addition of aliphatic amines to α,β-unsaturated compounds using molecular iodine as catalyst in dichloromethane at room temperature. Aromatic amines were found to be reactive under reflux in toluene.

experimental part, p. 379 - 382 (2010/04/03)
The efficient and very simple conjugate addition of aromatic and aliphatic amines to α,β-unsaturated carbonyl compounds under solvent-free conditions in the presence of catalytic amount of silicon tetrachloride is reported. The reaction of aryl and alkyl amines with different Michael acceptors gave the corresponding Michael adducts with simple catalyst and good to excellent yields.

, p. 141 - 143 (2007/10/03)
The addition of amines to conjugated alkenes has been carried out in water at room temperature very efficiently without any catalyst. Significant rate acceleration of this reaction is observed in water compared to organic solvents.
ZrOCl2·8H2O on montmorillonite K10 accelerated conjugate addition of amines to α,β-unsaturated alkenes under solvent-free conditions
Hashemi, Mohammed M.,Eftekhari-Sis, Bagher,Abdollahifar, Amir,Khalili, Behzad
, p. 672 - 677 (2007/10/03)
At room temperature, ZrOCl2·8H2O on montmorillonite K10 efficiently catalyzes conjugate addition of amines to a variety of conjugated alkenes such as α,β-unsaturated carbonyl compounds, carboxylic esters, nitriles and amides under solvent-free conditions. The catalyst can be recycled for subsequent reactions without any appreciable loss of efficiency.
Novel tertiary (meth)acrylates having lactone structure, polymers, resist compositions and patterning process
-
, (2008/06/13)
Novel tertiary (meth)acrylate compounds having a lactone structure are polymerizable into polymers having improved transparency, especially at the exposure wavelength of an excimer laser and dry etching resistance. Resist compositions comprising the polymers are sensitive to high-energy radiation, have a high resolution, and lend themselves to micropatterning with electron beams or deep-UV rays.
LiClO4 accelerated Michael addition of amines to α,β-unsaturated olefins under solvent-free conditions
Azizi, Najmedin,Saidi, Mohammad R.
, p. 383 - 387 (2007/10/03)
Several primary and secondary amines were added to α,β- unsaturated esters, nitriles, amides, and ketones to give the corresponding saturated amines mediated by solid lithium perchlorate under solvent-free and environmentally friendly conditions at room temperature.

, p. 569 - 571 (2007/10/03)
Novel electrophilic alkenes bearing an ionic liquid-type appendage have been prepared and used in Diels-Alder cycloadditions, 1,4-additions, Heck couplings and Stetter reactions; this new type of support allows easy monitoring of the reactions by NMR and MS as well as simple and efficient work-up and isolation procedures.
Air- and moisture-stable cationic (diphosphine)palladium(II) complexes as hydroamination catalysts X-ray crystal structures of two complexes
Li, Kelin,Horton, Peter N.,Hursthouse, Michael B.,Hii, King Kuok Mimi
, p. 250 - 257 (2007/10/03)
A series of cationic (diphosphine)palladium(II) complexes have been prepared and fully characterized, including two crystal structures. These complexes were evaluated as catalysts for the hydroamination of acyclic alkenes. The reactivity of the catalysts is dependent on the nature of the diphosphine ligand and the substituents on the amine and alkene substrates.
