Two New Publications on Pd Catalysis

This June started with two new papers related to palladium cross-coupling reactions.

First, we developed palladium-catalyzed functionalization of aryl- and heteroaryl chlorides with sodium tetrakis-(2-chloroethoxy)-borate salt, which is orthogonal to the simple nucleophilic replacement of the chloro function of the ethylene linker. Palladium Catalyzed Chloroethoxylation of Aromatic and Heteroaromatic Chlorides: an Orthogonal Functionalization of Chloroethoxy Linker. Subsequent amine substitution of the alkyl halide affords 2-aminoethoxy arenes. The paper entitled as "Palladium Catalyzed Chloroethoxylation of Aromatic and Heteroaromatic Chlorides: an Orthogonal Functionalization of Chloroethoxy Linker" and published in Organic & Biomolecular Chemistry (RSC).  For further reading, please, Click here.

Second, we disclose a novel catalytic method for the selective deprotection of trimethylsilylacetylenes in Sonogashira reaction. The reagent hexafluorosilicic acid, an inexpensive nontoxic compound, was used to promote the selective desilylation. This paper published by ACS in The Journal of Organic Chemistry as "Catalytic Activation of Trimethylsilylacetylenes: A One-Pot Route to Unsymmetrical Acetylenes and Heterocycles". For further reading, please, Click here.
