Metal-free nitro-carbocyclization of activated alkenes: A direct approach to synthesize oxindoles by cascade C-N and C-C bond formation

A novel and direct metal-free nitro-carbocyclization of activated alkenes leading to valuable nitro-containing oxindoles via cascade C-N and C-C bond formation has been developed. The mechanistic study indicates that the initial NO and NO2 radical addition and the following C-H functionalization processes are involved in this transformation.

Trifluoromethyl reagent as well as synthesis method and application thereof

The invention discloses a trifluoromethyl reagent as well as a synthesis method and application thereof, wherein the structural formula of the trifluoromethyl reagent is as shown in formula I in the specification. According to the invention, diphenyl trifluoromethylphosphine and iodomethane are used as raw materials, and are heated in an organic solvent to carry out an addition reaction to prepare the trifluoromethylation reagent. The method is simple and convenient in process, high in yield and capable of realizing 10-gram-level large-scale preparation; more importantly, the trifluoromethylation reagent can be used as a free radical and a nucleophilic reagent to be applied to free radical addition reaction and simple nucleophilic addition reaction to prepare different types of trifluoromethylation products, so that the method has important application value.

Photoinduced Hydroarylation and Cyclization of Alkenes with Luminescent Platinum(II) Complexes

Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron-deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible-light (410 nm) irradiation, affording anti-Markovnikov hydroarylated compounds in up to 95 % yield. Besides, a protocol for [Pt(O^N^C^N)]-catalyzed intramolecular photocyclization of acrylanilides to give structurally diverse 3,4-dihydroquinolinones has been developed.

Nickel-Catalyzed Transformation of Diazoacetates to Alkyl Radicals Using Alcohol as a Hydrogen Source

A nickel-catalyzed transformation of diazoacetates to α-carbonyl methylene radicals has been disclosed in the presence of hyperoxide using ethanol as a hydrogen source and solvent. This strategy is successfully applied in the formation of indolin-2-ones or 1,4-dicarbonyl compounds from acrylamides or enamides in moderate to good yields. These reactions undergo radical addition onto C-C double bonds followed by a cyclization/oxidation or an oxidation/hydrolysis process, respectively.

Iron-catalyzed aerobic difunctionalization of alkenes: A highly efficient approach to construct oxindoles by C-S and C-C bond formation

A novel iron-catalyzed efficient approach to construct sulfone-containing oxindoles, which play important roles in the structural library design and drug discovery, has been developed. The use of readily available benzenesulfinic acids, an inexpensive iron salt as the catalyst, and air as the oxidant makes this sulfur incorporation protocol very efficient and practical.

Ag-promoted azido-carbocyclization of activated alkenes via C - H bond cleavage

A sliver of silver: An efficient silver-promoted azido-carbocyclization of activated alkenes via a radical pathway has been developed. Azido oxindoles, which hold great potential for subsequent transformation of the azido unit, are efficiently constructed by this protocol. Radical addition and C - H functionalization processes are involved in this transformation with the formation of C - N and C - C bonds. Silver is observed to promote the single-electron oxidation process. Copyright

Palladium-catalyzed oxidative arylalkylation of activated alkenes: Dual C-H bond cleavage of an arene and acetonitrile

Not one but two: The title reaction proceeds through the dual C-H bond cleavage of both aniline and acetonitrile (see scheme). The reaction affords a variety of cyano-bearing indolinones in excellent yield. Mechanistic studies demonstrate that this reaction involves a fast arylation of the olefin and a rate-determining C-H activation of the acetonitrile. Copyright
