Description:
Two new dithiolene ligand precursors, containing fused TTF and alkyl thiophenic moieties 3,3'-{[2-(5-( tert -butyl)thieno[2,3- d ][1,3]dithiol-2-ylidene)-1,3-dithiole-4,5-diyl]bis[sulfanediyl]}dipropanenitrile (α-tbtdt, 1 ), and 3,3'-{[2-(5-methylthieno[2,3- d ][1,3]dithiol-2-ylidene)-1,3-dithiole-4,5-diyl]bis[sulfanediyl]}dipropanenitrile (α-mtdt, 2 ), were synthesized and characterized. The electrochemical properties of these electronic donors were studied by cyclic voltammetry (CV) in dichloromethane. Both compounds show two quasi-reversible oxidation processes, versus Ag/AgCl, typical of TTF donors at E 1 1/2 = 279 V and E 2 1/2 = 680 V for 1 and E 1 1/2 = 304 V and E 2 1/2 = 716 V in the case of 2 . The single-crystal X-ray structure of 1 and of a charge transfer salt of 2 , (α-mtdt)[Au(mnt) 2 ] ( 3 ), are reported. Beilstein J. Org. Chem. 2015, 11, 628–637. doi:10.3762/bjoc.11.71
