Mechanochemically micronised Na/NaCl; a superfine reductant†
Abstract
A free-flowing, homogeneous and non-pyrophoric powder of Na/NaCl is prepared via planetary ball-milling. The mechanochemically micronised Na/NaCl serves as a highly activated source of sodium and was used to prepare [(ArBDI)Mg]2 (BDI = HC{(Me)CNAr}2; Ar = Dipp, 2,6-i-Pr2C6H3; Mes, 2,4,6-CH3C6H2) via ball milling in 75 and 45 minutes, respectively.
