Abstract: | The thermolytic decomposition of Ph4SbSAr in organic solvents are reported. Solvent-derived products from decompositions in CCl4 and cyclohexane confirm the free radical nature of the reactions.Thermal decompositions of Ph3 (p-MeC6H4)SbSC6H4OMe-p, or Ph(p-MeC6H4)3SbSC6H4X(Xp-MeO or H) provide mixed triarylstibines,Ph3nSb(C6H4Me-p)n (n0, 1, 2 and 3), disulphide (XC6H4SSC6H4X), monosulphides (PhSC6H4X and p-MeC6H4SC6H4X), arenes, (PhH and PhMe) and biaryls (Ph2,PhC6H4Me-p and p-MeC6H4C6H4Me-p). |
