Reductive Coupling Reaction of Aryliminomethylferrocenes with Triethyl Orthoformate Induced by Low-valent Titanium

CHINESE JOURNAL OF CHEMISTRY, Issue 9 2001
Jun-Fang Gong
Abstract Reductive coupling reaction of aryliminomethylferrocenes FcCH = NAr[(1, Ar=QHs (a), p -ClC6H4 (b), p -BrC6H4 (c), p -CH3C6H4 (d), m -ClC6H4 (e)] with triethyl orthoformate (2) in Zn-TiCl4 system gave three kinds of products: 1, 3-diaryl-4, 5-diferrocenyl imidazolidines (3), N, N- disubstituted formamides (4), and 1, 2-diferrocenyl ethylene (5). 1H NMR spectra proved that all the compounds 3 obtained were dl -isomers. All the new compounds 3 and 4 were characterized by elemental analysis, 1H NMR, 13C NMR (for 3) and IR spectra. The molecular structure of 3c was determined by X-ray diffraction. [source]


Low-valent titanium induced reductive cyclization of nitro compounds and aliphatic ketones: facile synthesis of 3, 4-dihydro(2H) - 1, 2, 4-benzothiadiazine-1, 1-dioxides

CHINESE JOURNAL OF CHEMISTRY, Issue 5 2000
Wei-Hui Zhong
Abstract The intermolecular reductive cyclization of o -nitrobenzene-sulfonamides with aliphatic ketones induced by TiCl4/Sm system was studied and a series of 3, 3-disubstituted-3,4-dihydro(2H)-1,2, 4-benzothiadiazine-1,1-dioxides were synthesized in moderate to high yields under mild and neutral conditions.
