Catalytic Amount Of PdCl2 Research Articles

A NOVEL ACID-RESISTANT ACETAL-TYPE PROTECTIVE GROUP FOR ALCOHOLS

Abstract Alcohols are protected on treatment with 2-benzyloxy-3-fluoro-1-propene in the presence of a catalytic amount of PdCl2(COD), and the resulting acetals are easily deprotected to regenerate the parent alcohols by catalytic hydrogenation. The acetals, the protected alcohols, are rather resistant to acidic hydrolysis in comparison with common acetals because of the presence of fluoromethyl group.

Facile synthesis of acetylenecarboxylates by the oxidative carbonylation of terminal acetylenes catalyzed by PdCl 2 under mild conditions

Terminal acetylenes were converted to acetylenecarboxylates in high yields under atmospheric pressure of carbon monoxide at room temperature using a catalytic amount of PdCl 2 and a stoichiometric amount of CuCl 2.
