Abstract
The new compound [W IV2 OCl2L2] · DMF (2) has been synthesized by a redox reaction between WOCl4 and 2-pivaloylamino-6-acetonylisoxanthopterin (H2L, 1) in DMF medium. It bas been characterized by elemental analysis, spectroscopy and electrochemistry. Its reactivity towards Me3N → O has been followed both kinetically and stoichiometrically. The reaction follows substrate saturation kinetics and a large negative entropy of activation value points towards involvement of an associative mechanism. 1H-n.m.r. and c.v. data throw light on the role of a redox ‘non-innocent’ pterin ligand (1), in conferring reducing properties on the W(IV) atoms of (2).
