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

band-shape method has been used to determine exchange parameters for the systems PMe2Ph·BMe3, PMe2(NMe2)·BMe3, PMe3·BMe2Ph, and PMe2But·BMe3. Reactionsbetweencomplex and an excess of either donor or acceptor proceed by a dissociative mechanism. In dichloromethane at 27 °C, basicities towards BMe3 decrease in the order NMe3∼ PMe3 > PMe2But∼ PMe2(NMe2) > PMe2Ph P(CH2Ph)3 > PMe2(CF3)∼ PMe3O ∼ PMePh2.
