Abstract:
We report a modular synthesis strategy employing Rh-catalyzed C─H activation/annulation of aryl carboxylic acid and its derivatives with tailor-made dithienylacetylenes. This efficient cyclization approach enables rapid and flexible access to a series of novel dithienylethene derivatives featuring heterocyclic bridging architectures. The methodology streamlines traditional synthetic pathways and accelerates exploration of functional systems. The resulting materials exhibit tunable photochromism and aggregation-induced emission, demonstrating the successful integration of fluorescent heterocyclic units into the DTE framework.

Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
