Palladium-catalyzed arylation of α-allenic alcohols with hypervalent iodonium salts: Synthesis of epoxides and diol cyclic carbonates

Pd(0)-catalyzed arylation of the aryl-substituted α-allenic alcohols with hypervalent iodonium salts afforded substituted trans-epoxides. Alternatively, arylation of the alkyl-substituted α-allenic alcohols in the presence of K2CO3 afforded syn-diol cyclic carbonates and trans-epoxides in the presence of Cs2CO3.

Palladium-Catalyzed Carbonylative Cross-Coupling of Organoboranes with Hypervalent Iodonium Salts: Synthesis of Aromatic Ketones

The cross-coupling reaction of organoboronic acids and carbon monoxide (1 atm) with aryl-, alkenyl-, and alkynyliodonium salts at room temperature afforded unsymmetric aromatic ketones in moderate yields.

Manganese chloride-catalyzed cross-coupling and carbonylative cross-coupling of organostannanes with iodonium salts

The MnCl2·4H2O-catalyzed cross-coupling and carbonylative cross-coupling of organo-stannanes with hypervalent iodonium salts afforded biaryls and biaryl ketones, respectively.

Reductive Coupling Reaction of Hypervalent Iodonium Salts Catalyzed by Palladium-Zinc System

The ligand coupling of various diaryl- or alkynyl(phenyl)iodonium salts in the presence of diethylzinc and a palladium catalyst afforded biaryls or dialkynes under mild conditions.

Polymer-bound palladium-catalyzed coupling of allylic alcohols with hypervalent iodonium salts

The polymer-bound palladium-catalyzed cross-coupling reaction of allylic alcohols with hypervalent iodonium salts to form carbon-carbon bonds was achieved at room temprature under extremely mild and aqueous conditions even in the absence of base with very high activity in the Stille coupling reaction. The polymeric catalyst can be easily separated from a reaction mixture and reused more than 10 times with no decrease in activity

Palladium-Catalyzed Arylation and Vinylation of 2,3-Dihydrofuran with Hypervalent Iodonium Salts

The palladium-catalyzed arylation and vinylation of 2,3-dihydrofuran with aryl and alkenyl iodonium salts afforded 2-phenyl- or 2-alkenyl-2,5-dihydrofurans at room temperature in an aqueous medium.

Palladium-catalyzed coupling and carbonylative coupling of silyloxy compounds with hypervalent iodonium salts

Arylation and alkenylation of 1-ethoxy-1-trimetylsilyloxycyclopropane with diphenyliodonium tetrafluoroborate and alkenyliodonium tetrafluoroborate were accomplished by slow addition of silyloxycyclopropane to iodonium salts in the presence of Pd(OAc) 2 (2 mol %) and DME H 2O (4:1) to afford β-substituted ester. Alternatively, carbonylative coupling of silyloxypropane was carried out by slow addition of silyloxypropanes to iodonium salts under CO(1 atm) at room temperature in aqueous medium. The palladium-catalyzed coupling of ketene trimethylsilyl acetals with iodonium salts is also described.

Palladium-Catalyzed Coupling of Organo-Stannanes with Hypervalent Iodonium Salts

Abstract The palladium-catalyzed cross-coupling of organostannanes with iodonium salts in the presence of PdCl2(0.5 mol %) or Pd/C(2 mol %) as Pd(O) source was accomplished at room temperature under aqueous conditions.

Palladium-catalyzed coupling of allylic cyclic carbonates with iodobenzene and hypervalent iodonium salts

Palladium-catalyzed arylation of allylic cyclic carbonates with iodobenzene in the presence of Pd(OAc), as catalyst afforded the phenyl-substituted allylic alcohols via palladium oxygen β-elimination. However, palladium-catalyzed arylation, alkenylation, and alkynylation of allylic cyclic carbonates with iodonium tetrafluoroborates afforded the phenyl, alkenyl, and alkynyl-substituted allylic cyclic carbonates without reductive ring opening under aqueous and nouaqueous conditions.
