- Abstract
The reactions of 13 aliphatic ketones with tellurium tetrachloride has been studied with proton, carbon-13, and tellurium-125 NMR. Tellurium tetrachloride adds electrophilically to the α-carbon of the enol to form ketonyl tellurium trichlorides. Unsymmetric ketones gave mixtures of isomeric ketonyl tellurium trichlorides. Steric hindrance determines which ketonyl tellurium trichlorides form. Except for the ketonyl tellurium trichloride from 2-butanone, tellurium reacts preferentially with the least substituted α-carbon. Six methyl alkyl ketones also yielded appreciable amounts of diketonyl tellurium dichlorides. In all diketonyl tellurium dichlorides, tellurium is bonded to less hindered methylene carbons.
