Employing Water as the Hydride Source in Synthesis: A Case Study of Diboron Mediated Alkyne Hydroarylation

We present an approach to utilize water as the hydride source via Pd(II)/Pd(0) catalysis. As a case study, we have achieved a diboron mediated Pd(II)-catalyzed hydroarylation of alkynes using arylboronic acids. This approach not only complements conventional reactivity of Pd via Pd(0)/Pd(II) cycle for the hydroarylation but also utilizes water as the hydride source. We believe this would particularly be beneficial in utilizing water as a reagent.

ADDITION OF 5-MEMBERED AROMATIC HETEROCYCLIC COMPOUNDS TO ACETYLENES CATALYZED BY TETRARHODIUM DODECACARBONYL: SYNTHESES OF VINYL SUBSTITUTED AROMATIC HETEROCYCLIC COMPOUNDS

In the presence of a catalytic amount of Rh4(CO)12 furan adds to diphenylacetylene (1a) to give 1-(2-furyl)-1,2-diphenylethylene in a 80percent yield.Similarly, from 2-substituted furans are obtained the adducts (3e-3h), in which the furyls attach to the olefin at the 5-position of the rings, in good yields.Thiophene and N-methylpyrrole also react with 1a to afford the corresponding ethylenes.
