Organotin sulfides

Reaction with a sulfur-transfer reagent via an addition-elimination or substitution-elimination sequence. 

Reaction of an Sn-Sn bonded compound with elementary sulfur. 

Some examples of the first method are shown in equations 17-2,4 17-3,5 and 17-4.5-6

The acidity of the cyclopentadienes makes the cyclopentadienyltin compounds readily accessible97 either through the reaction of other cyclopentadienylmetal derivatives with tin(IV) halides (equation 9-44),99 or by acidolysis of an aminostannane with a cyclopentadiene (equation 9-45).100 101 Ferrocenylstannanes can also be obtained from ferrocenylmercury compounds and organotin sulfides (equation 9-54).102... 

Examples of some simple organotin sulfides are given in Table 17-1. 

The organotin sulfides are usually stable towards water and air, but react with acids such as HC1 to liberate H2S and give the corresponding tin halides. Bis(trimethyltin) sulfide (prepared in situ in THF as shown in equation 17-5) can be reduced with sodium, providing a convenient route to hexamethylditin (equation 18-14).7... 

Thiolato derivatives of main-group metals provide an interesting contrast to those of the transition metals, since despite the industrial application of compounds such as organotin sulfides, much remains to be done in the study of the chemistry of these interesting compounds. Methods for the preparation of organotin thiolates and selenolates have been reviewed, as have their physical and chemical properties. The preparation of tris(benzenethiolato)-indium by the reaction of InClj with NaSCgHj in methanol has recently been described, as have the properties of this compound. ... 

Typical thermal stabilizers for PVC are organic metal salts and soaps, phosphite, esters, and epoxy compounds. Examples are barium/zinc carboxylates [46], barium/cadmium carboxy-lates [47], calcium/zinc stearate [48], lead stearate [49],organotinmercaptides[50],organotin sulfides, organotin carboxylates[51], among others. Costabilizers such as 1,3-diketones, dihydropyridines, epoxy plasticizers, P-ketocarboxylic acid esters, phenolic antioxidants, a-phenylindols, and phosphates are used to improve the stabilizer s elfectiveness.
