Sulfonamide, Phenolate, and Directing Ligand-Free Indium Initiators for the Ring-Opening Polymerization of rac-Lactide

Abstract:

Reaction of In(CH2SiMe3)3 with H 2N2TsNpy or H2N 2TsNOMe gave the five-coordinate indium alkyls In(N2TsNpy)(CH2SiMe3) (14) and In(N2TsNOMe)(CH2SiMe 3) (15). The corresponding reaction with H2N 2TsNPh gave four-coordinate In(N 2TsNPh)(CH2SiMe3) (16). Reaction of H2N2TsNpy with In{N(SiMe3)2}3 gave the amide In(N 2TsNpy){N(SiMe3)2} (19). Reaction of Na2N2TsNpy with InCl3 in THF followed by LiOiPr gave the "ate" product In(N2TsNpy)(OiPr)Cl{Li(THF)} (21). The chloride complex In(N2TsNpy)Cl(py) (22...
