Behaviour of some lead(IV) and tin(IV) compounds in disulphoric acid

Add time:07/24/2019    Source:sciencedirect.com

Lead and tin tetraacetates form H2[Pb(HSO4)6] and H2[Sn(HSO4)6] in disulphuric acid which behave as weak acids of the system. Tin tetraethoxide, tetraphenyl tin, triphenyl tin chloride and diphenyl tin dichloride are solvolysed. Tetraethyl and tetrapropyl tin form the corresponding trialkyl tin cations, whereas trimethyl, tripropyl tin chlorides and dipropyl and diethyl tin dichlorides have ionisable chloride ions. Tributyl tin chloride, bis-tributyl tin oxide and dipropyl tin oxide are also solvolysed but bis-tripropyl tin oxide forms stannonium ion.
