Abstract
The synthesis and full characterization (mp, NMR, UV/vis, FTIR, and elemental analysis) of 13 bismuth aryloxides are reported. We have prepared bismuth aryloxides with alkyl, aryl, and allylic substituents on the aryl rings. Eleven of these bismuth aryloxides have been characterized with single crystal X-ray diffraction methods. Bismuth?donor interactions (donor = aryl, methoxy) are observed in several cases. Three unexpected bismuth oxo aryloxides (6c, 9c, 11c) were also isolated. Complex C77H102Bi4Br6O8 (6c) results from apparent C?H activation and Bi?C bond formation as a sideproduct in the synthesis of Bi(O-2,6-iPr2-4-BrC6H2)3 (6). Cluster 9c has a Bi32O56 core, and cluster C90H90Bi4Li2O12 (11c) is the second lithium bismuth oxo cluster reported to date.
