Reaction of the potassium salts of N-acylamido(thio)phosphates [4′-benzo-15-crown-5]NHC(S)NHP(Y)(OiPr)2 (Y = S, HLI; Y = O, HLII) with Zn(II) and Co(II) cations in aqueous EtOH leads to complexes of formulae Zn(LI,II - ...

A series of novel 4-(het)arylimidazoldin-2-ones were obtained by the acid-catalyzed reaction of (2,2-diethoxyethyl)ureas with aromatic and heterocyclic C-nucleophiles. The proposed approach to substituted imidazolidinones ...
