发明人：SUN HONGMEI
权利人:UNIV SOOCHOW
摘要:The invention discloses a mixed Ni(II) complex containing bisoxazoline-derived nitrogen heterocyclic carbene ligand and phosphite ligand and application thereof; the chemical formula of the mixed Ni(II) complex is Ni(NHC)[P(OR) 3 ]X 2 , wherein R is ethyl or isopropyl, X is bromine or chlorine, and NHC is a bisoxazoline-derived nitrogen heterocyclic carbene ligand. In the presence of magnesium shavings, the mixed Ni(II) complex containing bisoxazoline-derived nitrogen heterocyclic carbene ligand and phosphite ligand of the present invention can catalyze low-activity chlorinated aromatic hydrocarbons and fluorinated aromatic hydrocarbons with chlorinated benzyl compounds, respectively, reductive cross-coupling reaction at a single temperature, generating a diarylmethane compound in one step, providing a new method for the synthesis of diarylmethane compounds.

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.

摘要:Provided herein are a 2, 3-dihydrobenzo[d][1, 3]oxaphosphole derivative of formula (I) and a preparation method thereof. Compound I was constructed in utilizing tandem nucleophilic addition (or nucleophilic substitution) and intramolecular S NAr reaction. The method has the characteristics of simple operation steps, high yield, and mild reaction conditions. The technical problems of complex and harsh conditions in the synthesis of oxaphosphinine compounds in a conventional prior art were solved.
