A convenient preparation of DI-n-butyltin diphenoxides

Difunctional distannoxanes, XR2SnOSnR2X

“…In boiling benzene (80 °C), phenols react to give the diphenoxides, (ArO)R 2 SnOSnR 2 (OAr), 19 and hydroperoxides give the diperoxides, (R'OO)R 2 SnOSnR 2 (OOR') 20 whereas in tetralin (207 °C), phenols give the compounds R 2 Sn(OAr) 2 . 21 In boiling benzene, primary alcohols give the dialkoxides, (R'O)R 2 SnOSnR 2 (OR'), but secondary alcohols do not react in boiling benzene or toluene (111 °C). 22 The aerobic oxidation of the distannanes XR 2 SnSnR 2 X to the distannoxanes XR 2 SnOSnR 2 X (Scheme 1, reaction 5) is seldom used as a preparative method, but it represents one of the examples of the distannoxanes being formed adventitiously, and initially led to the two classes of compounds being confused.…”

Synthesis, Characterization, and Antibacterial Activity of Diorganotin(IV) Complexes of 4-Methylphenol

“…Of organotin complexes containing tin-oxygen bond, derived from hydroxides, oxides, alkoxides and phenoxides, peroxides, and alkyl peroxides, there are numerous studies concerning organotin alkoxides. The reactions of organotin chlorides with the sodium salt of the appropriate alcohol/phenol 25,26 and organotin oxide with phenols 27 are quite common and are frequently used. However, they do not always provide a successful synthetic route to organotin alkoxides and phenoxides because of the formation of tetraalkyl dialkoxydistannoxanes in the latter reaction.…”
