Butylstannoic acid

Phosphinic Acid Reactions. Reaction of n-butylstannoic acid with diphenylphosphate instead of a carboxylic acid also results in the formation of a drum composition [ n-BuSn(0) 02P (OPh)2] g (Chandrasekhar, V. Holmes, J. M. Day, R. 0. Holmes, R. R., unpublished work). However, when diphenylphosphinic acid is reacted with n-butylstannoic acid under reflux in toluene, a new structural form of tin is obtained (7 ). The reaction proceeds according to Equation 4 giving the stable oxide composition in 90% yield, mp 198-208°C dec. 

The oxide monobutyltin oxide [51590-67-1]> is a sesquioxide, C4H9Sn015, from which it is difficult to remove the last traces of water. It is an infusible, insoluble, amorphous white powder that forms when butyltin trichloride is hydrolyzed with base. The partially dehydrated material, butylstannoic acid [2273-43-0], is slighdy acidic and forms alkali metal salts. These salts, ie, alkali metal alkylstannonates, form when excess alkali is used to hydrolyze the organotin trichloride ...

The compositions and properties of aromatic aliphatic polyesters prepared from terephthalic acid, sebacic acid, butanediol, and butylstannoic acid (as a catalyst) are shown in Table 4.8 and Table 4.9.
