文摘
Benzylmethoxybis(2,4,6-triisopropylphenyl)tin (1) and benzylisopropoxybis(2,4,6-triisopropylphenyl)tin (2) were synthesized and characterized. Compound 1 exhibited good activity in the ring-openingpolymerization of 
-caprolactone, in a living fashion, under mild conditions. The polymerization was demonstratedto proceed via ring-opening of the monomer at the acyl-oxygen bond. The -caprolactone insertion product intothe Sn-OCH3 of the initiator was characterized, providing support for a "coordination-insertion" mechanism.
