Catalytic behavior of tetrahydroborate complexes of rare earth metals, Ln(BH 4 ) 3 (THF) x (1: ), for ring-opening polymerization (ROP) of six-membered cyclic esters, d-valerolactone (VL) and D,L-lactide (D,L-LA), was studied. The controlled polymerization of VL with 1-6 proceeded in THF at 60 C. T
