Qian, Xin published the artcileCatalytic double C-Cl bond activation in CH2Cl2 by iron(III) salts with Grignard reagents, Computed Properties of 457-68-1, the publication is Synlett (2011), 852-856, database is CAplus.
Cross-coupling of Grignard reagents with dichloromethane is achieved using iron(III) catalysts. Aryl- and benzyl-magnesium bromides show a range of activity toward double C-Cl bond activation resulting in the insertion of methylene fragments between two equivalent of the nucleophilic partner.
Synlett published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C13H10F2, Computed Properties of 457-68-1.
