Despite a formal negative charge on boron , no LiċB coordination is found in borataallene 1 . Instead, the Li ions are coordinated by the aryl C atoms and an allene C atom. In diboratabutadiene 2 , one Li ion is also coordinated by aryl C atoms. The other is coordinated by the butadiene unit and two Si methyl groups. Aryl = 2,4,6‐Me 3 C 6 H 2 .
