| Abstract: | Pentavalent bis(triorganosiloxy)triphenylantimony derivatives, Ph3Sb(OSiR3)2 (R = Me, Ph), were synthesized by reaction of triphenylantimony with trimethyl- or triphenylsilanol in the presence of tert-butylhydroperoxide by the mild reaction conditions (0-5 °C, 2 h). The reaction of triphenylantimony with diethanolamine in the presence of tert-butylhydroperoxide gave the cyclic compound Ph3Sb(OCH2CH2)2NH. The mixture of Ph3SbO and Ph3Sb(OCH2CH2NMe2)2 was obtained by the reaction of triphenylantimony with 2-(N,N-dimethylamino)ethanol in the presence of tert-butylhydroperoxide. |
