Abstract
The telomerization reaction of dienes with alcohols mediated by organopalladium complexes represents a versatile method to convert butadiene into value-added chemicals. The use of aromatic alcohols in the telomerization is still an under-explored area that has attracted increased interest in recent years. In this contribution, we examine the catalytic behaviour of a series of well-defined palladium N-heterocyclic carbene precatalysts (Pd-NHC) in the telomerization of butadiene with aromatic alcohols. The process was optimized by studying the influence of Pd/L ratio, of the base and of the pre-catalyst structure. The versatility of the method was tested employing a series of aromatic alcohols, including lignin-type phenols. In the context of biomass valorisation, an explorative study on the telomerization with lignin was carried out.
期刊介绍：
The Journal of Catalysis publishes scholarly articles on both heterogeneous and homogeneous catalysis, covering a wide range of chemical transformations. These include various types of catalysis, such as those mediated by photons, plasmons, and electrons. The focus of the studies is to understand the relationship between catalytic function and the underlying chemical properties of surfaces and metal complexes.
The articles in the journal offer innovative concepts and explore the synthesis and kinetics of inorganic solids and homogeneous complexes. Furthermore, they discuss spectroscopic techniques for characterizing catalysts, investigate the interaction of probes and reacting species with catalysts, and employ theoretical methods.
The research presented in the journal should have direct relevance to the field of catalytic processes, addressing either fundamental aspects or applications of catalysis.
