Triphenyltin carboxylates

Discrete structures are found generally for Ar3Sn02CR (Ar = Aryl). Many examples of triphenyltin carboxylates, with some exceptions, are known to adopt these structures. In these compounds the tin is... 

The formation of 1,1,2,2-tetraphenyldiacyloxyditins has also been observed in the reaction of triphenyltin hydride with benzoic, 2-thenoic, and furoic adds. The latter two acids also gave the simple triphenyltin carboxyl-ates, whereas acetic and propionic acids gave only the simple carboxylates (81). How the ditin compounds come about in these cases remains to be ascertained.

Aldehydes and ketones can be converted to ethers by treatment with an alcohol and triethylsilane in the presence of a strong acid or by hydrogenation in alcoholic acid in the presence of platinum oxide. The process can formally be regarded as addition of ROH to give a hemiacetal RR C(OH)OR", followed by reduction of the OH. In this respect, it is similar to 16-14. In a similar reaction, ketones can be converted to carboxylic esters (reductive acylation of ketones) by treatment with an acyl chloride and triphenyltin hydride. " ...
