- Photosensitive resin composition and uses thereof
-
The invention relates to a photosensitive resin composition that has the advantages of high developability, good hardness, and good sputtered resistance. The invention also provides a method for manufacturing a color filter, color filter and a liquid crystal display device. The photosensitive resin composition comprises an alkali-soluble resin (A), a compound containing an ethylenically unsaturated group (B), a photoinitiator (C), an organic solvent (D), a pigment (E), and a compound (F).

- Sulfoxide-Chelated Ruthenium Benzylidene Catalyst: a Synthetic Study on the Utility of Olefin Metathesis
-
We provide an experimental summary of selected advances in olefin metathesis methodology that were reported over the past decades. A stable and universal sulfoxide-chelated ruthenium olefin metathesis catalyst [RuCl2(SIMes)(=CH?C6H4?S(O)Ph)], SIMes=1,3-bis(2,4,6-trimethylphenyl)-4,5-dihydroimidazol-2-ylidene, was introduced and its application profile was studied in detail. A range of model substrates of natural origin was developed and successfully metathesized with variants of the reaction, such as ene–yne, cross, or ring-closing metathesis. All reported reactions were performed in non-pretreated solvents and in air to demonstrate the user-friendliness of the system. Besides the great functional group tolerance exhibited by the reported complex, its compatibility with multiple solvents was determined along with its air and moisture stability. Additionally, an interesting effect increasing the reaction efficiency was observed, if reactions were performed at temperatures around the solvent boiling point.

- A green way to γ-lactams through a copper catalyzed ARGET-ATRC in ethanol and in the presence of ascorbic acid
-
A 'green' ARGET-ATRC, for the CuCl[PMDETA] catalysed cyclo-isomerization of N-allyl-α-polychloroamides to γ-lactams is described. The process works efficiently (yields 78-96%), uses a bio-solvent, as ethanol, and exploits the reducing feature of ascorbic acid to limit, at a low level (2-4%), the amount of catalyst. To preserve the efficacy of the catalytic cycle, addition of Na2CO3 is essential, which quenches the HCl released during the CuCl[PMDETA] regeneration step. Profitable features of the process are: mild reaction temperatures (25-37 °C), relatively short reaction times (usually 5 h) and low solvent volumes (2 mmol of substrate/mL of ethanol). The method, upon stoichiometric adjustment, was also used for the synthesis of α,β-unsaturated-γ-lactams from N-(2-chloroallyl)-α- polychloroamides, via a tandem process involving an ATRC and a reductive [1,2]-elimination.

- Biphasic manganese carbonyl reactions: A new approach to making carbon-carbon bonds
-
A new, mild and practical biphasic method for conducting manganese carbonyl reactions, which lead to the formation of carbon-carbon bonds, has been developed: the mechanisms of these reactions can involve radical and/or ionic pathways.

- Marine compositions bearing preferentially concentrated domains of non-tin, organo anti-fouling agents
-
The present invention is addressed to a curable, marine anti-fouling composition of a thermoplastic or thermosetting binder, solvent, non-tin, organo antifouling agent, and optionally conventional additives, e.g. leaching agents, opacifying pigments, etc. The anti-fouling agents are found in preferentially-concentrated domains (hereinafter, often referred to as "PCD") in the cured compositions. The PCDs can be termed non-homogeneous, phase-separated, or incompatible in the system. The art term used in describing the PCDs of anti-fouling agent is not limitative of the invention as the disclosure herein will demonstate. Preferably, PCDs are created by forming an oligomeric adduct of the anti-fouling agent which adduct is formed into PCDs upon the curing of the composition. Additional techniques for forming PCDs of anti-fouling agent are revealed herein. The present invention also is addressed to new, low toxicity anti-fouling agents which comprise pesticide or herbicide compounds having a X factor of between about 0.01 and 3, a Z value for vinyl or aromatic compounds of between about 0.01 and 0.08, and an LD50 value of greater than 200 mg/kg against rats or mice. Such pesticide or algicide compounds broadly can be selected from heterocyclic compounds, aromatic compounds substituted with heteroatom substituents, various amino compounds, carbocyclic vinyl ether ketones, certain phospho compounds, certain polychlorinated carbocyclic and acyclic compounds, certain chlorinated carbocyclic carboxylates, antimony tartrate, boric acid, and cupric oleate. Exemplary aromatic compounds include diaromatic compounds linked with a sigma bond or with a carbon or heteroatom linkage, fused aromatic rings, and mono-aromatic compounds.

- Effect of Temperature on Atom Transfer Cyclization Reactions of Allylic α-Iodo Esters and Amides
-
Atom-transfer cyclizations of allyl iodoacetates and N-allyl-N-methyliodoacetamides are much more efficient at 80 deg C than at 25 deg C.At 80 deg C, β-(iodomethyl) lactones and lactams are formed rapidly and in good yield under standard atom-transfer conditions (sunlamp irradiation of iodide and 10percent hexabutylditin in benzene for 10-60 min).It is proposed that this temperature effect is responsible for some unusual observations by Jolly and Livinghouse in the cyclization of N-cyclohexenyl-N-methyliodoacetamide.The results suggest that the beneficial effect of temperature arises because an increase in the rate of rotation of t he OC-O or OC-N bond in the intermediate radicals begins to convert syn radicals (which cannot cyclize) to anti radicals (which can cyclize).Consistent with this hypothesis, the radical derived from N,N-diallyliodoacetamide (which always has a favorable arrangement for cyclization) closes with excellent efficiency at 25 deg C.
