- Light-induced synthesis of π-extended tetrathiafulvalenes incorporating ferrocenes: An efficient route for the synthesis of electron-donor materials
-
A new method for the synthesis of π-extended tetrathiafulvalenes was developed. The protocol is based on the exposure of 1,4-dithiafulvenes to sunlight or UV light at ambient temperature. In the resulting chalcogenofulvalenes the 1,3-dithiole ring systems are separated by conjugated spacers. Extended TTF analogues are obtained by insertion of linear π-conjugated spacers (C=C-C=C) of increasing dimensions between the two 1,4-dithiafulvenyl moieties. Georg Thieme Verlag Stuttgart.

- A SIMPLE SYNTHESIS AND SOME CHEMICAL PROPERTIES OF BENZO-1,4-DITHIAFULVENES
-
The synthesis of benzo-1,4-dithiafulvenes by a simple treatment of 2-substituted 1,3-benzodithiolium tetrafluoroborates - obtained starting from carboxylic acids or acyl chlorides and tetrafluoroboric acid/ ether complex - with acetonitrile water is reported.The reaction is very fast and affords the products in high over-all yields and under mild conditions.The reactions of benzo-1,4-dithiafulvenes with reducing agents (zinc/trifluoroacetic acid and acetonitrile, zinc/deuterated trifluoroacetic acid and acetonitrile, Raney nickel) and with oxidizing agents (hydrogen peroxide/ acetic acid, sodium hypochlorite, chlorine gas/water) are also reported.These reactions show the interesting synthetic potential of benzo-1,4-dithiafulvenes.
