  Fluorescent 3-Methylene-2,3-Dihydrochalcogenophenes Incorporated in a Rigid Dibenzobarrelene Skeleton

  摘要：

  The fluorescent 3-methylene-2,3-dihydroselenophene derivative (Phi(F) = 0.86 in CH2Cl2) incorporated in a dibenzobarrelene skeleton was synthesized by the reaction of a four-membered selenaplatinacycle with dimethyl acetylenedicarboxylate (DMAD) or reaction of bis(dibenzobarrelenyl) diselenide with DMAD in the presence of Pd(PPh3)(4) and PPh3. A fluorescent sulfur homologue (Phi(F) = 1.0 in CH2Cl2) was also synthesized by the reaction of bis(dibenzobarrelenyl) disulfide with DMAD in the presence of Pd(PPh3)(4). Selected chemical transformations of these diesters were also investigated.

  Thermal reactions of bis(dibenzobarrelenyl) dichalcogenides [(DbbS)2 and (DbbSe)2] with [Pd(PPh3)4] in toluene afforded novel mononuclear chalcogenide(dichalcogenolato)PdII complexes [Pd(EDbb-12-EDbb)(EDbb)(PPh3)] (E = S, Se) together with dichalcogenahexacyclo compounds. The reaction in the presence of PPh3 in toluene at 110 °C led to a cyclometalation to furnish the corresponding four-membered 1
