Triethyltin methoxide

Metal-Oxygen Compounds. Clear examples of the addition of transition metal alkoxides to acetylenes are not known however, the addition of trialkyltin alkoxides has been reported. Triethyltin methoxide, for example, reacts with dimethyl acetylenedicarboxylate to give the vinyl tin derivative XVI (63). 

Selective oxidation of alcohols to aldehydes and ketones in high yields continues to receive attention. Geraniol (8), as the triethyltin alkoxide, is oxidized with bromine and triethyltin methoxide no double-bond isomerization is reported,43 in contrast to...

The method is related to that of Saigo et (U. in which an alcohol is converted Into the triethyltin alkoxide by reaction with triethyltin methoxide an alddhyde or ketone is formed by oxidation of the alkoxide with bromine in the presence of triethyltin methoxide (6, 613). 

The products obtained from the reaction between triethyltin methoxide and A -hexyl- or N-phenylformamide were found to be identical with those obtained previously by addition of triethyltin hydride to the corresponding isocyanates (93, 94). The organotin-substituted carbamates obtained by the amidolysis reaction and those obtained by the addition of triethyltin methoxide to the corresponding isocyanate are, likewise, identical. 

It may be remarked that the reaction of triethyltin methoxide with the corresponding thioacylamides or thiocarbamates affords products containing a tin-sulfur rather than a tin-nitrogen bond.
