Reactions of Te–B heterocycles Te((Ph)C [double bond, length as m-dash]

C(C₆F₅))₂B(C₆F₅) 1 with alcohols is shown to afford species of the form Te((Ph)C [double bond, length as m-dash]

C(C₆F₅))₂BOR. The subsequent reaction with either 4-Br-C₆H₄CCH or 3-(C₄H₃S)CCH proceeds with the liberation of C₆F₅CCPh to give unsymmetrically substituted Te–B based heterocycles of the form Te((Ph)C [double bond, length as m-dash]

C(C₆F₅))(HC [double bond, length as m-dash]

CR)BOCH₂Ph.
