A simple and effective co-catalyst for ring-closing enyne metathesis using Grubbs I type catalysts: A practical alternative to "Mori's conditions"

"Catch-and-release": Simple alk-1-enes are effective at liberating buta-1,3-dienes from vinyl alkylidene ruthenium complexes, as well as undergoing alkene-alkylidene exchange with enyne substrates to regenerate the alk-1-ene. This ability to "catch-andrelease" ruthenium alkylidenes allows alk-1-enes higher than ethylene ("Mori's conditions") to be used as a co-catalysts in terminal enyne metathesis with the Grubbs generation I complex (L=PCy3).

Linear Paired Electrolysis—Realising 200 % Current Efficiency for Stoichiometric Transformations—The Electrochemical Bromination of Alkenes

The generation of bromine by oxidation of bromide anions at the anode and reduction of molecular oxygen at the cathode to hydrogen peroxide resulted in the overall formation of two molecules of Br2 (=four electron oxidation) by passing just two electrons through the solution. The bromine was used for the bromination of alkenes and thereby a linear paired electrolysis was attained which resulted in current efficencies of up to 200 %. Also, the diiodination of cyclohexene as well as the electrophilic aromatic bromination of an electron-rich arene were realised both in 168 % current efficiencies.

Method for preparing o-dibromo compounds from olefins

The invention relates to a method for preparing o-dibromo compounds from olefins, and the structural formulae of the o-dibromo compounds are as follows. The method comprises the following steps: dropwise adding a dichloromethane solution of dimethyl sulfoxide (1.5 equiv) into a dichloromethane solution of oxalyl bromide (1.5 equv) at a temperature of -10 DEG C, then dropwise adding a raw materialolefin, and then recovering the temperature to room temperature or carrying out heating to 30-40 DEG C, carrying out a reaction to obtain the corresponding o-dibromo compounds, wherein the yield is ina range of 79-97%.

Oxidative bromination reactions in aqueous media by using Bu4NBr/TFA/H2O2 system

Metal-free oxidative bromination reactions in aqueous media were performed using tetrabutylammonium bromide, trifluoroacetic acid, and hydrogen peroxide under mild conditions. Oxidative bromination reaction of alkenes was found to afford the corresponding vic-bromides. Furthermore, this oxidative bromination system is applicable to the oxidative bromination of alkynes, arenes, and 3,4-dihydronaphthalen-1(2H)-one. A gram-scale bromination reaction was also performed successfully.
