摘要:The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of the general formula n wherein: n M is ruthenium or osmium; n X and X 1 are each independently an anionic ligand; n L is a neutral electron donor ligand; and, n R, R 1 R 6 , R 7 , R 8 , and R 9 are each independently hydrogen or a substituent selected from the group consisting of C 1 -C 20 alkyl, C 2 -C 20 alkenyl, C 2 -C 20 alkynyl, aryl, C 1 -C 20 carboxylate, C 1 -C 20 alkoxy, C 2 -C 20 alkenyloxy, C 2 -C 20 alkynyloxy, aryloxy, C 2 -C 20 alkoxycarbonyl, C 1 -C 20 alkylthio, C 1 -C 20 alkylsulfonyl and C 1 -C 20 alkylsulfinyl.

标题 :Synthesis of combinatorial arrays of organic compounds through the use of multiple component combinatorial array syntheses
发明人：ARMSTRONG ROBERT W
权利人:UNIV CALIFORNIA; ARMSTRONG ROBERT W
摘要:The present invention relates to an array of compounds having a common core structure wherein the compounds of the array comprise the products of a multiple component combinatorial array synthesis having at least three components. The present invention also relates to the method of synthesizing that array. A further embodiment of the present invention relates to the use of solid phase synthesis to synthesize the combinatorial array of compounds. The present invention also relates to a method of creating a combinatorial array of compounds with a common core structure by identifying the desired core structure, identifying an MCCA reaction capable of generating that core structure, followed by preparing an array of compounds using the identified MCCA reaction according to the aforementioned method. The present invention also relates to a method for conducting in vitro assays of biological material using the combinatorial arrays of the present invention.

标 题 :High yield synthesis of hydroxyl-containing cationic photoinitiators
发明人：CRIVELLO JAMES V
权利人:POLYSET CORP
摘要:Synthesis use of a new class of diaryliodonium salt photo and thermal polymerization initiators in which the aryl groups are substituted with alkoxy group bearing hydroxy groups. Good to excellent yields are obtained of diaryliodonium salts in which the aryl groups are substituted with long chain alkoxy groups, which alkoxy groups also possess at least one hydroxyl moiety attached at the 2-position of an alkoxy group. The resultant salts have enhanced solubility when compared with their lower molecular weight counterparts. The hydroxyl groups serve as chain transfer agents; and, in cross linking UV-induced cationic polymerizations, the hydroxyl groups effect marked accelertion on polymerization rates. The salts also have excellent compatability with nonpolar monomers such as epoxidized oil and poly(1,2-butadience oxide) and provide further benefits when they are used along with copper cocatalysts in thermally curable polymer systems. In the latter form of cases, the secondary hydroxyl group serves as a reducing agent for the copper (II) complex.
