The NNNNN-pincer multidentate pyrrolyl rare-earth-metal amido-chloride complexes {η1:κ3-2,5-[CH3N(CH2CH2)2NCH2]2C4H2N}RECl[N(SiMe3)2] (RE = Y (2a), Sm (2b), Dy (2c), Er (2d), Yb (2e)) were synthesized by one step from reactions of [(Me3Si)2N]3RE(μ-Cl)Li(T
One-Pot Synthesis of C2 Symmetric and Asymmetric N,N′,N″-Substituted Guanidines from Aryl Isothiocyanates and Amines

Highly substituted guanidines were conveniently prepared through a one-pot reaction between aryl isothiocyanates and amines mediated by the Ph3P-I2/Et3N system. The C 2-symmetric N,N′,N″-substituted guanidines were readily accessed using a 1:2 molar ratio of an aryl isothiocyanate and an amine; while sequential addition of two different amines in equimolar ratios gave rise to asymmetric derivatives. Both primary and secondary amines were found to react preferentially with electron-deficient aryl isothiocyanates, rapidly providing guanidines in good yields under mild conditions.
The synthesis of some new sulfur-bearing various heterocyclic systems derived from asymmetrical N,N′-disubstituted thiourea derivatives
Saad, Hosam
, p. 1557 - 1567 (2007/10/03)
The heterocyclization of an asymmetrical N,N′-disubstituted thiourea (1a-d) in ring closure reactions with Br2/AcOH, ethyl chloroacetate, diethyl oxalate, diethyl malonate, and hydrazine hydrate led to the direct formation of sulfur-bearing var
