标题:Use of functionalized onium salts as a soluble support for organic synthesis
发明人：VAULTIER MICHEL; GMOUH SAID; HASSINE FATIMA
权利人:CENTRE NAT RECH SCIENT; UNIV RENNES
摘要:The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A₁⁺, X₁^-, wherein A₁⁺ represents a cation and X₁^- represents an anion.

摘要:A method of synthesizing a two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound having the structure: n nwhere Y is hydrogen, a thermally self-polymerizable acrylic, or a methacrylic group; R is an alkyl group of the formula —C m H 2m+1 , wherein the subscript m ranges from 1 to 6, or an alkylether group of the formula —(CH 2 CH 2 O) p Me, wherein the subscript p ranges from 1 to 5; R′ is an alkyl group; and the R′—(OY) x groups are attached to the phenyl rings of the triarylamine moiety either in a para position or a meta position and the subscript x ranges from 1 to 3. The compound may be synthesized by (a) synthesizing a diarylamine intermediate, (b) synthesizing a brominated 1,3,5-triazine intermediate as a three-arm core structure, and (c) forming the two-photon active tris(diarylamino-9,9-di(R)fluorenyl)-1,3,5-triazine compound by covalently joining the diarylamine and each arm of the three-arm core structure and removing the acetone protecting groups. The diarylamine intermediate may be synthesized by protecting tris-1,1,1-(hydroxymethyl)ethane, via a ketal formation with acetone, as an acetonide derivative; furnishing bromophenoxy-methyltrimethyl-1,3-dioxane from the acetonide derivative; and arylating aniline with the bromophenoxy-methyltrimethyl-1,3-dioxane.

标题:Process for the synthesis of phenols from arenes
发明人：MALECZKA JR ROBERT E; SMITH III MILTON R; HOLMES DANIEL; SHI FENG
权利人:UNIV MICHIGAN STATE
摘要:A process to synthesize substituted phenols such as those of the general formula RR'R''Ar(OH) wherein R, R', and R'' are each independently hydrogen or any group which does not interfere in the process for synthesizing the substituted phenol including, but not limited to, halo, alkyl, alkoxy, carboxylic ester, amine, amide; and Ar is any variety of aryl or hetroaryl by means of oxidation of substituted arylboronic esters is described. In particular, a metal-catalyzed C-H activation/borylation reaction is described, which when followed by direct oxidation in a single or separate reaction vessel affords phenols without the need for any intermediate manipulations. More particularly, a process wherein Ir-catalyzed borylation of arenes using pinacolborane (HBPin) followed by oxidation of the intermediate arylboronic ester by OXONE is described.

标 题:Synthesis of bromobiphenyls
发明人：LANG JOHN F; GURUSAMY NARAYANASAMY
权利人:MALLINCKRODT SPEC CHEM
摘要:Bromobiphenyls (such as 2-fluoro-4-bromobiphenyl) are synthesized by reacting together a phenylboronic acid (such as phenylboronic acid) and a bromoiodobenzene (such as 2-fluoro-4-bromoiodobenzene). The reaction generally takes place with the aid of a catalyst (such as palladium in a zero valance state) and an inert solvent (such as fluorobenzene). Control of temperature is very important to obtain both an acceptable reaction rate and an acceptable level of terphenyl byproduct.
