Pentaphenylantimony was reacted with furfural, acetophenone, and 4-(dimethy
lamino)benzaldebyde oximes in toluene to obtain tetraphenylantimony dioxima
tes. The configuration of the antimony atom, bond lengths and bond angles i
n Ph4SbON=CHC4H3O and 4-Ph4SbON=CHC6H4C6H4CH=ONSbPh4-4 were determined.
