•Phosphinimino-amine (PIA) supported Sc and Mg alkyl complexes are prepared.•PIA supported Sc dialkyl complex can initiate the polymerization of ethylene efficiently.•PIA supported Mg hydride complex is prepared.•PIA supported Mg hydride complex is can conduct the dearomatisation of pyridine.
Alkane elimination reaction of phosphinimino-amine ligand HL (L = (2,6-iPr2-C6H3)NC(Me)CHP(Cy2)N(2,6-Me2-C6H3)) with MgnBu2 and Sc(CH2SiMe3)3(THF)2, respectively, can afford the corresponding phosphinimino-amine supported magnesium monoalkyl complex LMgnBu(THF) (1) and scandium dialkyl complex LSc(CH2SiMe3)2 (2). 2 can initiate the polymerization of ethylene efficiently under the activation of [Ph3C][B(C6F5)4]. Magnesium hydride complex [LMgH]2 (3) can be easily obtained by the reaction of 1 and phenylsilane. The hydride species in 3 can conduct the dearomatisation of pyridine to give dearomatisation product 1,2-dihydropyridide (4).
