Organo-scandium and -yttrium complexes supported by a salicylaldiminato ligand

Reaction of a salicylaldiminato ligand with M(CH2-SiMe2Ph)(3)(THF)(2) (M = Sc, Y) leads to diastereoselective formation of highly thermally stable L2MR complexes whose reactivity with dihydrogen to form Group 3 metal hydrides is described.
