The preparation and characterization of zinc complexes supported by potentially tridentate biphenolate phosphane ligands are reported. The in situ prepared dilithium complexes of 2,2′‐tert‐butylphosphanylbis(4,6‐di‐tert‐butylphenolate) ([LtBu]2–) and 2,2′‐phenylphosphanylbis(4,6‐di‐tert‐butylphenolate) ([LPh]2–) react with ZnCl2 in tetrahydrofuran (THF) to produce lithium zincates Zn[LtBuLi(THF)]2 and Zn[LPhLi(THF)]2, respectively, regardless of the stoichiometry of the starting materials. Alkane elimination reactions of ZnEt2 with one equiv. of H2LtBu or H2LPh in THF generate Zn2(LtBu)2(THF) or Zn2(LPh)2(THF)2, whereas those employing two equiv. of the protio ligands afford Zn(LtBuH)2(MeCN) or Zn(LPhH)2(MeCN), respectively. The X‐ray structures of Zn[LtBuLi(THF)]2, Zn2(LtBu)2(THF), Zn2(LPh)2(THF)2, and Zn(LtBuH)2(MeCN) are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
