Ti(III) Catalysts for CO₂/Epoxide Copolymerization at Unusual Ambient Pressure Conditions.

ABSTRACT: Titanium compounds in low oxidation states are highly reducing species and hence powerful tools for the functionalization of small molecules. However, their potential has not yet been fully realized because harnessing these highly reactive complexes for productive reactivity is generally challenging. Advancing this field, herein we provide a detailed route for the formation of titanium(III) orthophenylendiamido (PDA) species using [LiBHEt₃] as a reducing agent. Initially, the corresponding lithium PDA compounds [Li₂(^ArPDA)(thf)₃] (Ar = 2,4,6-trimethylphenyl (^MesPDA), 2,6-diisopropylphenyl (^iPrPDA)) are combined with [TiCl₄(thf)₂] to form the heterobimetallic complexes [{TiCl(^ArPDA)}(μ-
