The power of trichlorosilylation: isolable trisilylated allyl anions, allyl radicals, and allenyl anions.

ABSTRACT: Treatment of hexachloropropene (Cl₂C[double bond, length as m-dash]C(Cl)-CCl₃) with Si₂Cl₆ and [nBu₄N]Cl (1 : 4 : 1) in CH₂Cl₂ results in a quantitative conversion to the trisilylated, dichlorinated allyl anion salt [nBu₄N][Cl₂C[double bond, length as m-dash]C(SiCl₃)-C(SiCl₃)₂] ([nBu₄N][1]). Tetrachloroallene Cl₂C[double bond, length as m-dash]C[double bond, length as m-dash]CCl₂ was identified as the first intermediate of the reaction cascade. In the solid state, [1]^- adopts approximate C _s symmetry with a dihedral angle between the planes running through the olef
