Abstract
To study the influence of electronics on catalytic polymerization properties independent from sterics, phosphinesulfonato Pd (II) complexes bearing remotely located substituents on the nonchelating P-bound aryls [κ2-(P, O)-(4-R-2-anisyl) 2 P C6H4SO2 O] Pd (Me)(dmso)(1a–e- dmso: 1a, R= CF3; 1b, R= Cl; 1c, R= H; 1d, R= CH3; 1e, R= OCH3) were prepared. The electron-poor complex 1a-dmso (4-CF3) undergoes the fastest insertion of methyl acrylate ...
