| dc.description.abstract | The reaction of potassium hexamethyldisilazide (K-HMDS) with 1 equiv. of the bulky formamidine N(Diep){double bond, long}C(H)NH(Diep) (DiepFormH, Diep = 2,6-Et<inf>2</inf>C<inf>6</inf>H<inf>3</inf>) in THF yields the half deprotonated compound [K(DiepForm)(DiepFormH)] (1), which exhibits suppressed reactivity with the hexamethyldisilazide anion. Reaction of 1 with n-BuLi gives the polymer [{Li(THF)<inf>2</inf>K(DiepForm)<inf>2</inf>}<inf>n</inf>] (2). Preparation of 1 in the presence of the chelating solvents 1,2-dimethoxyethane (DME) or N,N,N′,N″,N″-pentamethyldiethylenetriamine (PMDETA) gives the fully deprotonated species [{K<inf>3</inf>(DiepForm)<inf>3</inf>(DME)<inf>3</inf>}<inf>n</inf>] (3) and [{K(PMDETA)K(DiepForm)<inf>2</inf>}<inf>n</inf>] (6). The syntheses of compounds 1-3, 6 and related compounds, e.g. [{K<inf>3</inf>{N(Dimp)C(H)N(Dimp)}<inf>3</inf>(DME)<inf>3</inf>}<inf>n</inf>] (4) (Dimp = 2,6-Me<inf>2</inf>C<inf>6</inf>H<inf>3</inf>), are described. © 2007 Elsevier B.V.
