The heteroaromatic anion lithium N,N-diisopropyl-3-amino-1,3-thiaborolide (5) has been prepared by a multistep synthesis and has been converted to Cp*Ru complex 7 and Cp*ZrCl2 complex 8. On activation by excess methylaluminoxane (MAO), a solution of 8 is an active catalyst toward the polymerization of ethylene.
