Synthesis of 1,2,3-tripnictolide anions by reaction of group 15 Zintl ions with acetylene. Isolation of [E3C2H2](-) (E = P, As) and preliminary reactivity studies.

Journal article

Dimethylformamide solutions of K(3)E(7) (E = P, As) react with acetylene yielding the 1,2,3-tripnictolide anions [E(3)C(2)H(2)](-) (R = P (1), As (2)). Preliminary studies have shown that 1 and 2 displace labile ligands in [Ru(COD){η(3)-CH(3)C(CH(2))(2)}(2)] (COD = 1,5-cyclooctadiene) to yield the novel complexes [Ru(η(5)-E(3)C(2)H(2)){CH(3)C(CH(2))(2)}(2)}](-) (E = P (3), As (4)).
