Zinc-Catalysed Hydroboration of Terminal and Internal Alkynes

A regioselective hydroboration of alkynes has been developed by using commercially available zinc triflate as a catalyst, in the presence of catalytic amount of NaBHEt3. The reaction tolerates a wide range of terminal alkynes having several synthetically useful functional groups and proceeds regioselectively to furnish hydroborated products in moderate to excellent yields. This system shows moderate chemoselectivity towards terminal C≡C bond over terminal and internal C=C bond and internal C≡C bond.

Molecular daisy chains: Synthesis and aggregation studies of an amphiphilic molecular rod

A water-soluble cyclophane as the loop subunit, monofunctionalized with a molecular rod, has been synthesized to introduce a new binding motif for mechanically interlinked oligomers. It has been demonstrated that this hermaphroditic compound forms [c2]dai

Fluoro-substituted phenyleneethynylenes: Acetylenic n-type organic semiconductors

Fluoro-substituted phenyleneethynylenes are synthesized by Sonogashira coupling and acetylide-nucleophilic substitution of fluorobenzenes. Fluoro-substitution of benzenes enables deep LUMO potential, and CF 3-substitution provides high electron
