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