A new synthesis for methyl/trifluoromethyl organometallic compounds by low temperature cocondensation of trifluoromethyl radicals and main group methyl alkyls
The reaction of trifluoromethylradicals produced in a radio frequency discharge of hexafluoroethane with trimethylphosphine, tetramethyltin, dimethylmercury, tri-methylbismuth and tetramethyllead gave complexes with methyl and trifluoromethyl substituents. The compounds dimethyl(trifluoromethyl)phosphine, trimethyl(trifluoromethyl)tin, methyl(trifluoromethyl)mercury, bis(trifluoromethyl)mercury, dim

A fluoroform‐derived borazine CF3− transfer reagent is used to effect rapid nucleophilic reactions in the absence of additives, within minutes at 25 °C. Inorganic electrophiles spanning seven groups of the periodic table can be trifluoromethylated in high yield, including transition metals used for catalytic trifluoromethylation. Organic electrophiles included (hetero)arenes, enabling C−H and C−X
