Synthesis and characterization of pyrrole-based benzoxazine monomers and polymers

Applications of Clauson-Kaas Reaction in Organic Synthesis

Pyrrole-embedded organic molecules received a considerable importance due to their numerous biological and material applications. Hence, several synthetic strategies have been devised for the construction of diverse pyrrole analogues over the years. Among these, the Clauson-Kaas reaction is one of the most widely used protocols for the synthesis of various N-substituted pyrroles. This review briefly describes the Clauson-Kaas reaction along with modifications and a detailed account on its applications in the various sectors of organic synthesis.

Polypyrrole Derivatives: Preparation, Properties and Application

Polypyrrole (PPy) has attracted widespread attention due to its excellent environmental stability, high conductivity, simple synthesis, good biocompatibility, and reversible redox properties. PPy derivatives not only inherit the advantages of polypyrrole, but also have some unique properties. The side and N-site substitution of PPy can not only yield polymers with good solubility, but it also endows polymers with special functionalities by controlling the introduced functional groups. The performance of copolymers can also be adjusted by the type of monomer or polymerization ratio. In this review, an overview of the different types, main preparation methods, and the application prospects of PPy derivatives reported to date are summarized and presented. The current challenges and future opportunities in this research area are also prospected.
