WebThe structures of oximes 23 and 25 were confirmed by X-ray crystallography which showed clear evidence for co-ordination of the tin by the nitrogen. The aldehyde 22 was also converted into the hydrazone 26, loss of a phenyl substituent from the tin not being observed in this case although the double-bond had been reduced in situ.
