Replacement of RCO2H by dilute HNO3 has afforded the nitrate analogue Rh(Lal)(PPh3)2(NO3) (7). Species of type 5 are susceptible to aldiminium → aldehyde hydrolysis in a dichloromethane−acetone−water mixture with concomitant chloride dissociation, furnishing Rh(Lal)(PPh3)2Cl (8a), from which the N-bonded nitrite Rh(Lal)(PPh3)2(NO2) (8b) has been generated metathetically.
