Tri alkylstibines are sensitive to oxygen, and in some cases they ignite spontaneously in air. Trimethyl stibine [594-10-5] C3H2Sb, may explode on... 

In volume terms the most important class of fire retardants are the phosphates. Tritolyl phosphate and trixylyl phosphate are widely used plasticisers which more or less maintain the fire-retarding characteristics of PVC (unlike the phthalates, which reduce the flame resistance of PVC products). Better results are, however, sometimes obtained using halophosphates such as tri(chloroethyl) phosphate, particularly when used in conjunction with antimony oxide, triphenyl stibine or antimony oxychloride. 

Xenon difluoride has been used to oxidize a number of antimony compounds [102, 109] in yields ranging from 73 to 98%. Elemental fluorine oxidized tris(pen-tafluorophenyl)stibine to tris(pentafluorophenyl)stibine difluoride in 98% yield [706]. Oxidative fluonnation of stibines has also been accomplished with iodine pentafluoride [707]. 

Al-Sb heterocycles were obtained for the first time in our group from reactions of dialkylalanes R2A1H and tris(trimethylsilyl)stibine Sb(SiMe3)3. 

Analogous to 1,2,3-benzazadiphospholes (Section 4.22.10) 1,3,2-benzazaphosphaarsole (39) and 1,3,2-benzazaphosphastibole (37) results from the condensation of 2-aminophenylphosphine (38) and tris(dimethylamino)arsine or stibine (Scheme 9) <93PS(76)45>. 

Tris(organoplumbyl)stibines have been prepared by condensing organolead chlorides with stibine (equation 28).97... 

Antimony trichloride does not react with dimethylamine to give dimethylaminostibines (compare arsenic trichloride). The more vigorous reagent Me2NLi, however, gives a good yield 1 of tris(dimethylamino)stibine, a colourless, air- and moisture-sensitive liquid (Table 13 equations 29 and 30105). 

Tris(dialkyl)stibines react with sulfur dioxide (equation 33), affording tetraalkylsulfurous diamides and an unidentified antimony/nitrogen compound.101... 

Brcunig109 observed the unusual coupling reaction of tris(trimethylstannyl)stibine when oxidized by air (equation 36).

Tri(o-tolyl)stibine reacts with mercury(II) halides in cold benzene solution to form 1 1 complexes. Under reflux the stibine is chlorinated to R3SbCl2 by HgCl2, which is reduced to Hg2Cl2. In refluxing THF the products are RHgCl and R2SbCl.529 Triarylbismuthines... 

The same method may be used for the preparation of tri- -tolyl-stibine. Starting with 282 g. of -bromotoluene (Org. Syn. 6, 21) and proceeding in the same manner as described there was secured 150-157 g. (77 -80 per cent of the theoretical amount) of crude tri-/>-toIyl-stibine. This product purified by recrystallization from methyl alcohol or ether melts at 125-126°. The reaction is somewhat more vigorous in this case and sometimes cooling is necessary at first. 

Numerous alkyl and aryl phosphine, arsine and stibine compounds are described as being silver solvents. Examples are tris(p-hydroxyphenyl)phosphine and bis(2-carboxyethyl)methyl-phosphine.72...
