Convenient one-pot synthesis of tert-butyldimethylantimony

Article abstract of DOI:10.1021/om00038a072

tert-Butyldimethylantimony, (t-Bu)Me₂Sb, was prepared by a one-pot reaction of SbCl₃ with 1 equiv of (t-Bu)MgCl at -50°C followed by 2 equiv of MeMgBr at 0°C in diethyl ether. (t-Bu)Me₂Sb was isolated in 64% yield (based on SbCl₃) after fractional vacuum distillation (63°C at 30 Torr) and can be used as a precursor in the chemical vapor deposition of antimony-containing semi-conductor materials.
