Bismuth alkoxide
WebTwo separate routes to bismuth alkoxides have been examined: the metathesis of the metal halides with NaOR, (R = t-butyl, and diisopropylphenoxide) and the alcoholysis of bismuth amides, Bi (NR 2) 3, [R = N (SiMe 3) 2] The alcoholysis preparation gives high yields of several alkoxides suitable as precursors to the high T c materials.
