Bis(ethyleneselenothio)-tetrathiafulvalene (BEST-TTF) and -tetraselenafulvalane (BEST-TSF) have been synthesized using the following two consecutive cyclization methods: (1) one-pot construction of the inner 1,3-dichalcogenole ring from THP-protected 2-(ethynylthio)ethanol and (2) intramolecular transalkylation on a selenium atom toward the formation of the outer dihydrothiaselenin ring. The X-ray crystallographic analysis of BEST-TSF revealed that its molecular and crystal structures are essentially similar to those of BEDT-TTF and related selenium variants.
