Abstract

Diazaphospholidine-sulfonato Pd (II) complexes [{κ2-P, O-(N-Ar2C2H4N2P) C6H4SO3} PdMe (L)] 1-L (L= dmso, pyridine, lutidine, or μ-LiCl (solvent); 1a: Ar= Ph, 1b: Ar= 2- MeC6H4, 1c: Ar= 2-MeOC6H4, 1d: Ar= 2, 4, 6-Me3C6H2, 1e: Ar= 2, 6-i Pr2C6H3, 1f: Ar= 2, 6- (p-tolyl) 2C6H3) were prepared and structurally characterized. The regioselectivity of methyl acrylate (MA) insertion into the Pd–Me bond is entirely inverted from> 93% 1, 2-insertion ...
