Peroxymonosulfate ion, HSO Οͺ 5 , as Oxone, readily converts phosphorus(V) esters of thiols into the phosphorus(V) and sulfonic acids. The esters were Ph 2 PO β’ SC 6 H 4 R(p) with R = MeO (1a), Me (1b), H (1c), Cl (1d) and NO 2 (1e), (EtO) 2 PO β’ SPh (2), Ph 2 OI β’ SEt (3) and PhPO(OEt)SEt (4). React

Peroxymonosulfate ion, HSO 5 Γ, as Oxone in aqueous H 2 SO 4 , oxidizes sulfides [MeSC 6 H 4 X(p), X = Me, H, NO 2 ] to sulfoxides and converts aryl thiobenzoates [PhCOSC 6 H 4 X(p), X = Me, H] and thiol phosphorus(V) esters [Ph 2 POSPh, (EtO) 2 POSPh, Ph 2 POSEt, Ph(EtO)POSEt] into the acids and su
Lithium ester enolates, prepared by the reaction of lithium N-isopropylcyclohexylamide (LIICA) with esters at -78' (eq. 1); react with acid chlorides at this same low temperature to provide satisfactory yields of the corresponding S-keto esters (eq. II). This procedure represents an exceedingly vers
