Halo-l-alkyl Organo Tellurium Compounds

Dibutyl tellurium promotes alkylidenation of aldehydes by dibromomalonic esters  

Diisopropyl tellurium intercepted primary carbon radicals, generated by the photolysis of acyl derivatives of iV-hydroxy-2-thiopyridone, and released isopropyl radicals that were trapped by olefins.  

Aryl organo tellurium compounds that have an electronegative group or atom bonded to the tellurium-bearing carbon atom can be considered to be acetals of telluroaldehydes, telluroketones, or telluroketenes. Such compounds derived from telluroketones are not known. 

Heterocyclic lithium tellurolates reacted with dichloromethane at 20 . Chloromethyl organo tellurium derivatives, the products of the first step in these reactions, could not be isolated. It was postulated that the second nucleophilic substitution is much faster than the first one.
