A palladium-catalyzed, iodine-mediated electrophilic annulation between 2-(1-alkynyl)biphenyl and disulfide has been developed. With the combination of PdCl(2) and I(2), a variety of 2-(1-alkynyl)biphenyls underwent electrophilic annulations with various disulfides successfully to afford the corresponding 9-sulfenyl phenanthrenes in moderate to excellent(More)
A novel protocol for the 1,2-addition reactions of electron-deficient aryl aldehydes with arylboronic acids using an inexpensive and environmentally benign iron catalyst is reported. In the presence of FeCl(3) and 2-(di-tert-butylphosphino)biphenyl, 1,2-addition reactions of various electron-deficient aryl aldehydes with arylboronic acids provided the(More)
