Cationic magnesium hydride [MgH](+) stabilized by an NNNN-type macrocycle
Abstract
A magnesium hydride cation [(L)MgH](+) supported by a macrocyclic ligand (L = Me(4)TACD; 1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclo-dodecane) has been prepared by partial protonolysis of a mixed amide hydride [(L)MgH2Mg{N(SiMe3)(2)}(2)] and shown to undergo a variety of reactions with unsaturated substrates, including pyridine.
