in neat (no solvent) React. (vac. line, no solvent) at room temp. for 10 min.; Removal of Me3SnCl by passing the mixt. through a trap cooled to -95°C (toluene). IR and NMR spectra indicate presence of resulting compounds in approximately equimolar amt.;

in neat (no solvent) Warming mixt. of equimolar amt. of starting materials (condensed at -196°C) to -80°C (30 min) and then gradually to 10°C.; Removal of Me3SnCl by passing the mixt. through a trap cooled to -95°C (toluene). NMR spectrum indicate presence of major resulting compounds, with small amt. of SiF3SiHBr2 and unreacted SiF3SiFHBr.;
