Notes:
Both E- and Z-(β-stannylvinyl)phosphines are readily converted to the corresponding phosphine oxides by KMnO4 in acetone. However, the less reactive oxidising agents MnO2 and O2 react selectively with only the E isomers. N.m.r. studies indicate that this may be due to interactions between the phosphorus lone pair and the triorganostannyl moiety in the Z-isomer, which make the latter less susceptible to attack. N.m.r. parameters for the phosphines and their oxides are compared.
