Selective mono reduction of bis-phosphine oxides under mild conditions.
Bis-phosphine oxides can be selectively reduced to bis-phosphine monoxides under exceptionally mild conditions using triflic anhydride and a thiol.
متن کاملSelective conversion of alcohols and phenols to tetrahydropyranyl ethers catalyzed with N-chlorosaccharin under mild and solvent-free conditions
An efficient method is described for the mild and rapid tetrahydropyranylation of alcohols and phenols using a catalytic amount of N-chlorosaccharin (1 mol %) and 3, 4-dihydro-2H-pyran under solvent-free condition at room temperature. Benzylic alcohols and phenols containing electron withdrawing or donating groups in various positions of phenyl ring, cinamyl alcohol, primary, ...

متن کاملCopper-catalyzed oxidative arylation of heteroarenes under mild conditions using dioxygen as the sole oxidant.
Arylation of heteroarene has been intensively studied over the past few years because aryl-substituted aromatic heterocycles are known to exhibit interesting biological activities and are also useful as electronic materials. Numerous methods have been reported to successfully construct this motif by transition-metal-catalyzed cross-coupling and most of them required expensive transition-metal c...
متن کاملMild and selective base-free C-H arylation of heteroarenes: experiment and computation.
A mild and selective C-H arylation strategy for indoles, benzofurans and benzothiophenes is described. The arylation method engages aryldiazonium salts as arylating reagents in equimolar amounts. The protocol is operationally simple, base free, moisture tolerant and air tolerant. It utilizes low palladium loadings (0.5 to 2.0 mol% Pd), short reaction times, green solvents (EtOAc/2-MeTHF or MeOH...
