摘要

An improved synthesis of unsymmetrical tetrathiafulvalenes (TTFs)(5 ac, 5 fg, 7) is presented which results in higher yields of unsymmetrical TTFs when compared to existing methods. The synthetic method consists of pre-equilibration of thiones containing electron withdrawing groups with P (OEt) 3 at the minimum temperature where a reaction occurs as determined by 31P NMR, followed by the slow addition of the thiones to be coupled ( ...
