Abstract The synthesis of unsymmetrical biaryls with a methylthiogroup is achieved using the air‐stable palladium–phosphinous acid complexes, [(t‐Bu)2P(OH)]2 PdCl2 (POPd), as the catalyst. A great variety of substituted bromobenzenes having electron‐withdrawing and electron‐donating functional groups in para and meta positions have been successfully coupled with 3‐methylthiophenylboronic acid.
The preparation of sulfur-containing aryl and heteroaryl vinyl co-monomers via Suzuki-Miyaura cross-coupling between the corresponding mercaptomethyl arylboronates and in situ-generated vinyl bromides is described. Surface-enhanced Raman scattering (SERS) studies of the target compounds on gold nanoparticles confirmed their potential as spectroscopic tags in the fabrication of SERS-encoded polymers for combinatorial screening and biomedical diagnostics.

Molecular electronics demands complex functional molecules with multiple pathways connecting electrode leads. We report the synthesis and study of a set of molecules based on a fluorene-like design in which atomic connectors are used to introduce two pathways for conductance. This manuscript details the structural demands and underlying rationale for developing high conductance in these complex molecular circuit components.
