Synthetic routes to lead(II) derivatives of aromatic 1,2-diols and orthoquinones

The Reaction of 3,6‐di‐tert‐butyl‐o‐benzoquinone with tin amalgam: Synthesis and structure of tin catecholato complexes

“…Germanium reacts with 3,5-di-tert-butylo-benzoquinone slowly (boiling toluene, 12 days) to give GeQ 2 , GeQ 3 , or GeQ 4 (Q-one of the reduced or nonreduced form of 3,5-di-tert-butyl-obenzoquinone) complexes depending on the initial ratio of reactants [2]. Lead reacts with o-quinones more rapidly to form lead(II) catecholate or bis(o-semiquinonate) derivatives [3,4]. The reaction between tin and o-chloranil in refluxing toluene produces bis(tetrachlorocatecholate)tin(IV) [5].…”

Cost efficient preparation of lead aminoalkoxides directly from lead(II) oxide

“…Lead oxoisopropoxide has also been obtained via anodic oxidation of lead in isopropanol [8] while lead alkoxides and/or oxoalkoxides have been prepared by alcoholysis of lead bis(trimethylsilyl)amide or by metathesis of lead acetate or lead chloride with alcohol or sodium alkoxides [1,9,10]. More recently, aromatic diols and orthoquinone derivatives have been prepared from elemental lead [11]. Some complex lead salts with aminoalcohol and aminoalkoxide ligands [12][13][14][15] have been prepared, some directly from lead oxide, however no molecular aminoalkoxides were reported via this route.…”

“…The slightly weaker interaction between TPA‐PDO and Pb 2+ ions may be that Pb 2+ and 9,10‐phenanthrenedione can only form a semi‐ quinonate structure, that is to say, only one carbonyl group can interact with Pb 2+ ion without chelation effect of two carbonyl groups, which is supported by a previous report.
