Pentaalkoxy Tellurium Monofluorides

Pentaalkoxy tellurium monofluorides were formed by fluorination of tetramethoxy telluriums by reaction of cw-tetramethoxy tellurium difluoride with sodium methoxide in methanolS by the action of anhydrous hydrogen fluoride on hexamethoxy tellurium, and by the condensation of primary alcohols with tellurium hexafluorideS None of these compounds was isolated. Their presence in the reaction mixture was detected by F-NMR spectroscopy.
