The molecule 2,5-difluoro-7,7,8,8-tetracyanoquinodimethane
(F2-TCNQ) is an organic semiconductor with many promising
properties,
including high charge mobility (μ). However, an efficient gram-scale
synthesis of F2-TCNQ has not been fully documented. Herein,
we report a synthesis of F2-TCNQ via a three-step sequence
that affords F2-TCNQ in 58% cumulative yield. This synthesis
was used to prepare more than 1 g of F2-TCNQ.
