“…It is known that electrochemical Mg deposition is impossible from solutions containing simple ionic Mg salts (such as MgCl 2 , Mg(ClO 4 ) 2 , etc.) in commonly used aprotic solvents (such as alkyl carbonates, esters, and acetonitrile) [6,7]. However, magnesium can be reversibly deposited electrochemically in the systems without the passivating phenomena, such as ethereal solutions of Grignard reagents (RMgX, R = alkyl, aryl groups; X = halide: Cl, Br) [7][8][9][10], amidomagnesium halides [11,12], Mg(BR 2 R 2 ) 2 (R = alkyl and R = aryl group) [2,11], Mg(AX 4−n R n R n ) 2 (A = Al, B; X = Cl, Br; R, R = alkyl or aryl groups, and n + n = n) [13,14], and PhMgCl-AlCl 3 [15].…”
