A practical and convenient Co-catalyzed alkylation method for the facile introduction of various alkyl chains into organic electronically significant heteroaryl compounds, including thiophenes, furans, selenophenes, and pyrroles, is reported. Under well-optimized reaction conditions, a wide range of alkylated heteroaryl compounds have beeen efficiently prepared in moderate to good isolated yields.
A heterocyclic fused selenophenes and a method of making a heterocyclic fused selenophenes of formula (1):
wherein X is S or Se, Y is S or Se, wherein one or both of X and Y is Se, R is a substituent group. The monomer being capable of polymerization to form an electrically conductive polymer or oligomer.

marked effect on their binding affinities. The compound bis(2‐fluoro‐4‐hydroxyphenyl)selenophene (2 f) has the highest relative binding affinity (RBA) of 24.3 for ERβ. In transcription assays, most selenophenes were found to exhibit partial to full agonist activity for both ER subtypes, with compounds bis(2‐methyl‐4‐hydroxyphenyl)selenophene (2 b), bis(4‐fluoro‐3‐hydroxyphenyl)3‐bromoselenophene (6 f),
Rational design and optimization of selenophenes with basic side chains as novel potent selective estrogen receptor modulators (SERMs) for breast cancer therapy
Selenophenes with basic side chains showed excellent antagonist activity for ERs and increased antiproliferative activity than that of 4OHT in MCF-7 cells.
