A new series of N<sub>2</sub>O tridentate ligands HL<i><sup>n</sup></i><sup></sup> (<i>n</i> = 2−5) have been prepared through
<i>N</i>-methylation or <i>N</i>-benzylation of 2-<i>N</i>-(2-pyridylmethyl)aminophenol (HL<sup>1</sup>). Treatment of
these ligands with WO<sub>2</sub>Cl<sub>2</sub>(DME) (DME = 1,2-dimethoxyethane) in the presence of
triethylamine leads to the formation of <i>cis</i>-dioxotungsten(VI) complexes WO<sub>2</sub>(L<i><sup>n</sup></i><sup></sup>)Cl (<i>n</i> = 1−5).
Reaction of WO<sub>2</sub>(L<sup>1</sup>)Cl with Me<sub>3</sub>SiCH<sub>2</sub>MgCl gives the alkyl derivative WO<sub>2</sub>(L<sup>1</sup>)(CH<sub>2</sub>SiMe<sub>3</sub>), which has been structurally characterized.
