1,1-Carboboration to tellurium–boron intramolecular frustrated Lewis pairs†
Abstract
The tellurium acetylide Ph(CH2)2TeCCPh reacts with boranes via 1,1-carboboration to give a series of borylated vinyl telluroethers. The product Ph(CH2)2TeC(Ph)C(C6F5) B(C6F5)2 reacts with phenylacetylene and iodine to give novel tellurium–boron heterocyclic compounds.
