摘要：

Evidence is given that the 1,3-dimesitylimidazoline-2-ylidene ruthenium alkylidene complex (4) demonstrates more efficient ADMET depolymerization of polybutadiene than the well-known metastasis catalysts RuCl2(=CHPh)(PCy3)2 (3) and the alkoxy-imido molybdenum alkylidene (1). This new complex is capable of the rapid depolymerization of the trisubstituted unsaturations in linear and cross-linked polyisoprene under very mild conditions.
