Abstract
The heteroaromatic anions 2-(diisopropylamino)-1,2-thiaborolide(2a), 1-ethyl-2-phenyl-1,2-azaborolide(2b), and 2-(diisopropylamino)-1,2-oxaborolide(2c) have been prepared by a multi-step synthesis using the Grubbs ring-closing metathesis. Reactions of 2a, 2b, and 2c with Cp*ZrCl 3 afforded the corresponding Zr(IV) complexes 3.
