Synthesis and reactions of 4H-1,4-telluraborine†
Abstract
The B(C6F5)3-catalyzed reaction of the 1,4-telluraborine, Te(PhCC(C6F5))2BOCH2Ph 2 with PhSiH3 gives Te(PhCC(C6F5))2BH 3. Compound 3 acts as a synthetic precursor to Te(PhCC(C6F5))2BCl 4 and Te(PhCC(C6F5))2B(THF)(O3SCF3) 5. In addition, 3 undergoes reactions with alkenes, alkynes, ketones and aldehydes to give a series of hydroboration products, 6–16.
