Substituted guanidines were synthesized by the guanylation of amines with carbodiimides using Zn-Al hydrotalcite (Zn-Al HT) catalyst. Zn-Al HT was prepared by co-precipitation method and characterized by X-ray powder diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Raman and Thermogravimetric-Differential Thermal Analysis (TG-DTA). The heterogeneous catalyst afforded moderate to good yields (~50-60 %) of substituted guanidines in toluene at 110?C in 12 h. The catalyst was recovered quantitatively by simple filtration and reused for three cycles with consistent activity. The XRD and FTIR studies of the used catalyst shows no variation in the structure of the catalyst even after three recycles. Indian Academy of Sciences.

Insertion of 2,6-iPr2C6H3N(Li)SiMe3 or PhN(Li)SiMe3 to the CN bond of Me2NCN or PhCN afforded the lithium complexes [Li(2,6-iPr2C6H3)NC(NMe2)NC(NMe2)N(SiMe3)]2 (1a) and [Li(PhNC(Ph)NSiMe3)]2 (1b). Complexes 1a and 1b were used as precursors to react with AlCl3 affording [(2,6-iPr2C6H3)NC(NMe2)NC(NMe2)N(SiMe3)]2AlCl (2) and [(PhNC(Ph)NSiMe3)]2AlCl (3), respectively. The structures of 2 and 3 were presented. Both 2 and 3 exhibit good activity to catalyze the addition reaction of arylamines to N,N'-diisopropylcarbodiimide.
