摘要

•Telomerization of pure and diluted 1,3-butadiene with methanol was catalyzed by two Pd-systems.•Diluted butadiene resulted in lower activity for Pd-TPP, but surprisingly higher activity for Pd-IMes.•For Pd-IMes the effective reaction rate is a strong function of base strength and concentration.•Model-based kinetic analysis revealed different mechanisms for Pd-TPP and Pd-IMes.
