Abstract

An efficient and straightforward procedure for the synthesis of HFIP esters-containing 2H-benzopyrans has been established through palladium-catalyzed one-pot cyclization/carbonylation reaction of substituted propargyl ethers with HFIP by using formic acid as the CO precursor. A diverse set of 2H-benzopyrans have been formed with HFIP esters as attractive functional groups in moderate to excellent yields. This protocol features broad substrate scopes and no manipulation of toxic CO gas.

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.
