Reactions of triphenylstibine with tert-butyl- and triphenyl-silyl hydroperoxides

The influence of some triphenylantimony(V) catecholates and o‐amidophenolates on lipid peroxidationin vitro

“…The increase of TBARS level can be rationalized by the possible reaction between Ph 3 Sb and primary products of lipid oxidation – LOOH as well as hydrogen peroxide presenting in tissues and cells . It is known that interaction of R 3 Sb (R = Alk, Ar) with organic hydroperoxides; H 2 O 2 leads to the oxidation of metal to the pentavalent state with the formation of R 3 SbO or R 3 Sb(OOR′), which undergoes hydrolysis to R 3 SbO . Earlier, triphenylantimony(V) oxide was shown to oxidize thiols to the corresponding disulphides .…”

One-step synthesis of pentavalent triphenylantimony derivatives Ph3Sb(OSiR3)2, Ph3Sb(OCH2CH2)2NH and Ph3Sb(OCH2CH2NMe2)2: X-ray molecular structure of Ph3Sb(OSiMe3)2

“…These compounds were described by element analysis and melting-point [13,14], and compound 1 -by IR spectroscopy only [13].…”

“…The tert-BuOOH-mediated oxidative method has not been used for the preparation of disiloxytriorganoantimony derivatives, R 3 SbðOSiR 0 3 Þ 2 . The compounds of this type have been synthesized in two or three-step sequences, involving the oxidation of triorganoantimony to triorganoantimony(V) dichloride, followed by reaction with sodium silanolate or with silanol in the presence of ammonia [13,14]. …”

Oxidation of triphenylantimony with 4-hydroperoxy-2-hydroxy-3,4,6-triisopropylcyclohexa-2,5-dienone or 3,4,6-triisopropyl-1,2-benzoquinone

“…Various phenyl derivatives of antimony(V) can be pre pared by the oxidative method, 3 to be more precise, by the reaction of triphenylantimony(III) with hydroperoxide and compounds containing labile hydrogen (RC(O)H, RC(O)OH, etc.). The characteristic feature of dienone 2 is that it contains simultaneously the hydroperoxide and hydroxy groups.…”
