Reactions of the Trimethylsilyl Ion with 1,2-Cyclopentanediol Isomers in the Collision Region of a Triple Quadrupole Instrument

Ion-molecule reactions with the trimethylsilyl ion were used to distinguish between cis- and trans-1,2-cyclopentanediol isomers.The ion kinetic energy of + was varied from 0 eV to 15 eV (center of mass frame of reference).At low ion kinetic energies (+.The cis-1,2-cyclopentanediol isomer favors decomposition of + to yield the hydrated trimethylsilyl ion + at m/z 91.For the trans isomer, the formation of the hydrated trimethylsilyl ion is an endethermic process with a definite threshold ion kinetic energy.

An Efficient Deprotection of 2,6-Bis(trifluoromethyl)phenylboronic Esters via Catalytic Protodeboronation Using Tetrabutyl ammonium Fluoride

We herein describe an efficient deprotection of 2,6-bis(trifluoromethyl)phenylboronic esters, which serve as effective protective groups for 1,2- or 1,3-diols in various organic transformations, via protodeboronation by using a catalytic amount of tetrabutylammonium fluoride (TBAF).

Selective transition-metal-free vicinal cis-dihydroxylation of saturated hydrocarbons

A transition-metal-free cis-dihydroxylation of saturated hydrocarbons under ambient reaction conditions has been developed. The described approach allows a direct and selective synthesis of vicinal diols. The new reaction thereby proceeds via radical iodination and a sequence of oxidation steps. A broad scope of one-pot dual C(sp3)-H bond functionalization for the selective synthesis of vicinal syn-diols was demonstrated.
