## Abstract Living cationic ring‐opening polymerization of ϵ‐caprolactone (CL), δ‐valerolactone (VL) and 1,3‐dioxepane‐2‐one (6) was achieved at room temperature by using zirconocene borate complex catalysts. Respective block copolymerization of CL with VL or with cyclic carbonate 6 was also succes

Successful room temperature ring-opening polymerization (ROP) of e-caprolactone and d-valerolactone has been carried out using SmX 2 (X = I, Br, and cyclopentadienyl (Cp)) catalysts. SmI 2 in the presence of metallic Sm was found to have enhanced reactivity as room temperature ROP initiator for lact
Phosphoraneiminato complexes of transition metals containing the NPR 3 À group are known in many coordinationchemical variations [1] as a result of varying bonding modes. In complexes with metal ions in low oxidation states (i, ii) the NPR 3 À group acts as m 3 -N bridging ligand, in medium oxidati
## Abstract The ring‐opening polymerization (ROP) of __ε__‐caprolactone (__ε__‐CL) using lanthanide thiolate complexes [(CH~3~C~5~H~4~)~2~Sm(μ‐SPh)(THF)] ~2~ (1) and Sm(SPh)~3~(HMPA)~3~ (2) as initiators has been investigated for the first time. Both of 1 and 2 were found to be highly efficient ini
## Abstract Poly(β‐hydroxyalkanoate)s (PHAs) are a class of aliphatic polyesters that can be efficiently synthesized by ring‐opening polymerization (ROP) of β‐lactones. The case of chiral racemic β‐substituted β‐lactones is particularly appealing since these monomers open the way to original tactic
