Abstract

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.
