“…Oxidative cyclization of saturated alcohols by lead tetraacetate leading to tetrahydrofuran derivatives was originally discovered in the late 1950s and mainly pursued by Mihailovic and co-workers . Ryu, Tsunoi, and Sonoda reported that the oxidative carbonylation of saturated alcohols leading to δ-lactones can be conveniently achieved with the aid of this one-electron oxidation system .…”

“…This remote carbonylation reaction is suited for primary and secondary alcohols having primary or secondary δ-carbons. Radicals at the δ-carbon are generated by 1,5-hydrogen transfer reaction from carbon to oxygen . The roles of LTA are to generate the alkoxy radical in the initial step 49 and to oxidize the acyl radical to an acyl cation in the final step.…”

“…We have investigated the feasibility of using readily available lead tetraacetate in very modest quantities for facilitating product purification after ring-closing metathesis (RCM) and here report our widespread success with this technology. Pb(OAc) 4 has long been recognized to be an oxidant having a broad range of uses . Notwithstanding, its reactions with organometallics have largely been limited to the liberation of cyclobutadienes from their Fe(CO) 3 complexes .…”
[formula: see text] Addition of a very modest amount of lead tetraacetate (1.50 equiv relative to the amount of Grubbs catalyst) to ring-closing metathesis reaction mixtures effectively removes all colored ruthenium and phosphine impurities to deliver colories reaction products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
