Abstract
AbstractWe report the synthesis of cinchonine and hydrocinchonine derived surfactants by reacting with various mono alkylating agents (hexyl, octyl, octadecyl, dodecyl bromides) and di‐alkylating agent such as α,α’‐p‐xylene‐di‐bromide. A series of chiral surfactants have been used to stabilize palladium nanoparticles (NPs) which are water soluble. These Pd NPs were utilized in asymmetric Suzuki cross coupling reaction of naphthalene boronic acids with substituted naphthalene bromides to get binaphthalenes and terephenylenes. It was observed that, the surfactant's alkyl‐chain length and the palladium source played a major role in this catalytic reaction. The high solubility and positive zeta potential of gemini‐surfactant (GS) stabilized Pd NPs make them attractive as a potential candidate for the synthesis of binaphthalenes and terephenylenes with high yields.
