Lewis-acid induced disaggregation of dimeric arylantimony oxides

The previously known dimeric arylantimony oxides (Ph3SbO)2 and [2,6-(Me2NCH2)2C6H3SbO]2 were disaggregated by the Lewis acid B(C6F5)3 giving rise to the formation of the Lewis pair complexes Ph3SbOB(C6F5)3 and 2,6-(Me2NCH2)2C6H3SbOB(C6F5)3 having short bipolar single Sb-O bonds.
