Application

N,N′-Di-tert-butylcarbodiimide can be used:
  • As a reagent for the guanylation of aryl amines catalyzed by lanthanum amides.
  • To prepare dichloroimidazolidine-4,5-dione by reacting with oxalyl chloride, which is a key intermediate for the synthesis of N,N′-diamidocarbenes.
  • To prepare the iridium complex of benzamidine named Ir(FMeppy)2(N,N′-di-tert-butyl-4-methyl-benzamidine).

It is demonstrated that the cyclopentadienyl-free simple lanthanide amides [(Me(3)Si)(2)N](3)Ln(mu-Cl)Li(THF)(3)(Ln = La, Sm, Eu, Y, Yb) and Ln[N(SiMe(3))(2)]3 (Ln = Y, Yb) are highly efficient catalysts for the guanylation of both aromatic and secondary amines with a high activity under

The synthesis of the first stable, five-membered N,N'-diamidocarbenes (DACs), including a differentially N-substituted derivative, was achieved via the reduction of a geminal dichloride precursor using potassium. Key differences between the reactivity of the five-membered DACs and their six-membered congeners were
