Expedient Synthesis of Substituted Thieno[3,2-b]thiophenes and Selenopheno[3,2-b]selenophenes Through Cascade Cyclization of Alkynyl Diol Derivatives
Thieno[3,2-<i>b</i>]thiophenes are used as key components in optoelectronic materials, porous hydrogen-storage hosts, organic solar cells, and polymer semiconductors. A step-efficient synthetic protocol was proposed herein for obtaining multisubstituted thieno[3,2-<i>b</i>]thiophene and selenopheno[3,2-<i>b</i>]selenophenes in moderate to good yields via the bisulfur/biselenium cyclization of alkynyl diols with I<sub>2</sub>/Na<sub>2</sub>S<sub>2</sub>O<sub>3</sub> or selenium. Using this strategy, substitution patterns were obtained for backbone modification in functional materials.
