Tetrahydrofuran → Bis(tributylstannyl)acetylene

Participants

Reaction Steps

In synthetic route `C1` of FIG. 1, an alternate two step process for preparing BFPE consistant with the route in Sutherlin et al., Macromolecules, v.19, p.1260-1265 (1986) is shown. The first step is coupling commercially available tri-n-butyltin chloride (Aldrich Chemicals, Milwaukee, Wis.) with lithium acetylide ethylenediamine complex. These precursors are heated to reflux in anhydrous tetrahydrofuran (THF) under an argon blanket to form bis(tri-n-butylstannyl)ethyne. The THF solution of bis(tri-n-butylstannyl)ethyne is subsequently washed and then dried over anhydrous sodium sulfate.
