Abstract

Abstract : The reaction of (Ph3 SbO)2 and [2, 6-(Me2 NCH2 )2 C6 H3 SbO]2 with B(C6 F5 )3 provided the donor acceptor complexes Ph3 SbOB(C6 F5 )3 and 2, 6-(Me2 NCH2 )2 C6 H3 SbOB(C6 F5 )3 having significantly shorter Sb–O bonds than their parent compounds. Abstract : The previously known dimeric arylantimony oxides (Ph3 SbO)2 and [2, 6-(Me2 NCH2 )2 C6 H3 SbO]2 were disaggregated by the Lewis acid B(C6 F5 )3 giving rise to the formation of the Lewis pair complexes Ph3 SbOB(C6 F5 )3 and 2, 6-(Me2 NCH2 )2 C6 H3 SbOB(C6 F5 )3 having short bipolar single Sb–O bonds.
