First iron-catalyzed guanylation of amines: a simple and highly efficient protocol to guanidines
The first iron-catalyzed guanylation of amines is reported. Commercially available Fe(OAc)2 acts as an excellent catalyst for the addition of amines to carbodiimides. The reaction is broadly applicable to a variety of primary, secondary, and heterocyclic amines, and tolerates a wide range of functionalities allowing the easy preparation of a large family of guanidines. The low price and low tox...

The reaction between vinylene trithiocarbonate and chlorosulfonyl isocyanate proceeds by initial attack of thiocarbonyl on the isocyanate carbon.
متن کاملAn amidato divalent ytterbium cluster: synthesis and molecular structure, its reactivity to carbodiimides and application in the guanylation reaction.
A divalent ytterbium amidate 1 ([Yb3L6]·2C7H8 for short) was synthesized via amine-elimination of Yb[N(SiMe3)2]2(TMEDA) with an amide proligand N-2,6-diisopropylphenylbenzamide HL (L = 2,6-iPr2C6H3NC(O)Ph) and structurally characterized to be a trinuclear symmetric cluster. Further studies on the reduction of iPrN[double bond, length as m-dash]C[double bond, length as m-dash]NiPr by complex 1 p...
متن کاملCopper-catalyzed bis-arylations of alkenes leading to oxindole derivatives.
A simple and practical copper-catalyzed approach to oxindole derivatives by copper-catalyzed bis-arylation of N-alkyl-N-phenylacrylamides with diaryliodonium triflates has been developed under mild conditions, and the method is of tolerance towards some functional groups in the substrates.
متن کاملRuthenium-catalyzed hydrovinylation of N-acetylenamines leading to amines with a quaternary carbon center.
A catalytic hydrovinylation of N-acetylenamines with ethylene is reported. This new hydrovinylation reaction is catalyzed by a ruthenium hydride complex, RuHCl(CO)(PCy(3))(2), providing a series of N-acetylamines with a quaternary carbon center with up to 99% yield.
