Published: December 2017

The B(CF)-catalyzed reaction of the 1,4-telluraborine, Te(PhC[double bond, length as m-dash]C(CF))BOCHPh 2 with PhSiH gives Te(PhC[double bond, length as m-dash]C(CF))BH 3. Compound 3 acts as a synthetic precursor to Te(PhC[double bond, length as m-dash]C(CF))BCl 4 and Te(PhC[double bond, length as m-dash]C(CF))B(THF)(OSCF) 5. In addition, 3 undergoes reactions with alkenes, alkynes, ketones and aldehydes to give a series of hydroboration products, 6-16.
