Oxidation in organophosphorus chemistry: Potassium peroxymonosulphate

One‐step transformation of ammonium dialkyl phosphoroselenoates into dialkyl phosphoramidates

“…The observed formation of the ammonium phosphates 5a-c and 11 in these reactions can be due to the direct oxidative deselenization of 1 and 8 by 2 and/or 3, similar to the well-known oxidative desulphurization of organic thioacids of phosphorus as well as their salts [19][20][21]. Alternatively, the observed formation of ammonium phosphates 5a-c and 11 result most probably from the participation of water in this reactions.…”

“…Similarly, high yield formation of bis(thiophosphoryl)disulfides in the oxidation of phosphorodithioic acids and their salts with nitric acid, nitrogen oxides [14][15][16][17], hydrogen peroxides [6,7], and dimethyl sulfoxide (DMSO) [18] was also observed. On the other hand, the oxidative desulfurization of phosphino-, phosphono-, and phosphorothioic acid esters in their reactions with DMSO [19,20] as well as potassium dialkyl phosphorothioate in the reaction with peroxymonosulfate (Oxone R ) [21], were reported. Recently, we described [22] the quantitative formation of bis(dialkoxyphosphinyl) disulfide as a major product of the oxidation reaction of ammonium dialkyl phosphorothioate by iodoxybenzene.…”

Magnetic CoFe2O4Nanoparticles as an Efficient Catalyst for the Oxidation of Alcohols to Carbonyl Compounds in the Presence of Oxone as an Oxidant

“…[21][22][23][24][25][26][27][28][29] In this paper, cobalt ferrite nanoparticles were synthesized by co-precipitation method. 30 We have shown that CoFe 2 O 4 MNPs are an active and reusable catalysts for oxidation of alcohols with oxone in the presence of water at room temperature (Scheme 1).…”

Formation of a Dicyanotriorganophosphorane from the Reaction of Triphenylphosphane with Phenylselenocyanate

“…1 J(Se-P) = 738 Hz). [22] The formation of Ph 3 PSe suggests that PhSeCN behaves to some degree similarly to KSeCN, which is routinely used to oxidize R 3 P to R 3 PSe, [23] although the resonance remained a minor product when the sample was monitored over several days. The reaction was monitored over 48 h, with a number of different species being observed ( Table 1).…”
