Scandium Reduced Arene Complex: Protonation and Reaction with Azobenzene.

ABSTRACT: The reactivity of the reduced anthracene complex of scandium [Li(thf)₃ ][Sc{N(tBu)Xy}₂ (anth)] (2-anth-Li) (Xy=3,5-Me₂ C₆ H₃ ; anth=C₁₄ H₁₀ ^2- , thf=tetrahydrofuran) toward Brønsted acid [NEt₃ H][BPh₄ ] and azobenzene is reported. While a stepwise protonation of 2-anth-Li with two equivalents of [NEt₃ H][BPh₄ ] afforded the scandium cation [Sc{N(tBu)Xy}₂ (thf)₂ ][BPh₄ ] (3), reduction of azobenzene gave a thermolabile, anionic scandium reduced azobenzene complex [Li(thf)][Sc{N(tBu)Xy}₂ (η² -PhNNPh)] (4), which slowly lost one of the anilide ligands to form the neutral scandium azobenzene complex dimer [Sc{
