The choice ofortho-alkynylaryl vinylsilane1awas motivated by the notion that alkynyl and vinyl groups could possibly trap radicals to assemble complex silacycles under blue light-emitting diodes (LEDs) irradiation. After an extensive screening of various reaction parameters, we were pleased to find ...
First, we examined the reaction of1awith a range of arylboronic acids. Arylboronic acids (3) bearing electron-donating and electron-withdrawing groups were well tolerated, and useful functional groups such as acetyl, cyano, formyl, ester, nitro, and vinyl groups were compatible, affording the corr...

A mild and general method for the conversion of aryl, heteroaryl, and vinyl bromides into the corresponding iodides was developed utilizing a catalyst system comprising 5 mol % of CuI and 10 mol % of a 1,2- or 1,3-diamine ligand. A variety of polar functional groups are tolerated, and...
Electrophilic substitution of the vinyl hydrogen atom in alkenyl alkyl ethers, 2-bromoethenyl alkyl ethers, and ketene acetals readily occurs under the action of phosphorus trihalides in the presence of an organic base to yield 70-98% of... MA Kazankova,IG Trostyanskaya,IV Efimova,... - ...
