Reduction of N,N′-di(2,6-diisopropylphenyl)carbodiimide (DippNCNDipp) by [SmL2(thf)2] (1) (L = N,N′-bis(2,6- diisopropylphenyl)formamidinate, DippNC(H)NDipp) in PhMe gave [Sm(L) 3] (2) in good yield. An analogous reaction of 1 with N,N′-dimesitylcarbodiimide (MesNCNMes) gave [SmL2(MesNC(H)NMes) ] (3). In contrast, reduction of N,N′-dicyclohexylcarbodiimide (CyNCNCy) by 1 in PhMe gave mixture of products from which [SmL2(CyNC(CH 2Ph)NCy)] (4) and [SmL2(CyNC(H)NCy)] (5) were isolated by fractional crystallisation. Using thf as the reaction solvent, solely compound 5 was crystallised. Reactions of [Sm(L)2(CCPh)(thf)] (6) with the carbodiimides RNCNR (R = Cy, Mes) gave [Sm(L)2(RNC(CCPh)NR)] (R = Cy (7) or Mes (8)) which are analogues of 4. No reaction was observed between 6 and DippNCNDipp. The Royal Society of Chemistry 2010.
