Three‐Step Synthesis Toward Fluorene‐Based Non‐Fused‐Ring Acceptors for Organic Solar Cells
Applying a simple three step synthesis strategy leads to two fluorene‐based non‐fused‐ring electron acceptors, FHM‐Cl and FHM‐F for organic solar cells. The chlorinated variant delivers markedly higher efficiency due to broader light harvesting and favorable molecular packing, resulting in improved charge transport and reduced recombination losses ...

Synthesis of 9-Alkylidene-9H-fluorenes by a Novel Palladium-Catalyzed Rearrangement
In the presence of a palladium catalyst and NaOAc, aryl iodides react with 1-aryl-1-alkynes to afford 9-alkylidene-9H-fluorenes in good yields. This process appears to involve (1) oxidative addition of the aryl iodide to Pd(0), (2) alkyne insertion, (3 ...
