In a simple exchange reaction zirconacycle 1 is converted into the new heterocycles 2 and 3 by treatment with Ar′GaCl 2 and Ar′InBr 2 , respectively. Gallacyclopentadiene 2 is monomeric and its five‐membered ring is planar. The cyclopentadiene ring and the aryl ring are nearly orthogonal owing to steric interactions. Compound 2 can be converted readily into a (C 5 H 5 )Co complex. Ar′ = 2,4,6‐ t Bu 3 C 6 H 2 .
