The most useful reaction in the synthesis of symmetric tertiary stibines is the conversion of antimony trihalides with organometallic compounds, such as trialkylaluminums, trialkylaluminum etherates, Grignard reagents, organolithium, and organosodium derivatives, respectively, in ether, tetrahydrofuran, or benzene. The latter three types of reagents are useful in the synthesis of aliphatic as well as aromatic stibines. Triarylstibines are also formed by treating antimony trihalides with aryl halides and sodium or magnesium in benzene or ether and by diazotization of aromatic amines in the presence of antimony trichloride in an acid medium followed by a decomposition of the diazonium intermediates with zinc dust.
