Abstract
1,3-Dithiol-2-ylphosphonate esters (3a-d) with a dibenzo-tetrathiafulv alene unit were synthesized directly from trialkylphosphite and 6,6'-d ioxo- (2a, c) and lthio)-2,2'-bi-1,3,5,7-tetrathia-s-indacenylidenes ( 2b, d). The influence of the type of trialkylphosphite, of the reactio n temperature and the solvent on the regioselectivity of the reaction was studied. In toluene the tristetrathiafulvalene (4c) was exclusivel y obtained from 2c.
