Synthesis and Structure of Boron–Bithiazole Complexes

The syntheses of the first reported p‐block complexes of the bithiazole moiety are reported, namely [(tBuBTz)BBr2][Br] (3), and [(PhBTz)BBr2][Br] (4) (tBuBTz = 4,4′‐di‐tert‐butyl‐2,2′‐bithiazole and PhBTz = 4,4′‐diphenyl‐2,2′‐bithiazole). Compounds 3 and 4 were prepared via reaction of equimolar quantities of the appropriate bithiazole ligand with BBr3. The molecular structures of 3, and the known compound PhBTz (2) were established using single‐crystal X‐ray diffraction techniques.
