Tin Tetrachloride

The N-trimethylsilyl compounds of the cyclic imides derived from cis-cyclohexan-1,2-dicarboxylic acid, cis-4-cyclohexen-1,2-dicarboxylic acid and phthalic acid were prepared. Reaction of the N-silylated cyclic imides 2 and 10 with 1,2,3,5-tetra-O-acetyl-β-ᴅ-ribofuranose in the presence of tin tetrachloride yielded the appropriate unusual ribonucleosides 4 and 12 whereas 14 led only to traces of the ribosylated derivative. The silylation and ribosylation sites in the aforementioned bicyclic imides were proved by 1H, 13C, and 29Si NMR spectroscopy and compared with data found for the monocyclic imides N-succinimide and N-maleinimide.

Tin Tetrachloride

Co-ordination complexes between diesters of α,ω-dicarboxylic acids and titanium tetrachloride, tin tetrachloride, and zirconium tetrachloride have been prepared. The analytical results, the infrared spectra, the melting points, and the molecular-weight determinations indicate that for the titanium and zirconium complexes, two types of complexes are obtained, one having a general formula MX4•1 diester in which chelate rings from five to nine atoms are formed and the other one, 2MX4•1 diester in which there are two 4-membered rings per complex molecule. With tin tetrachloride only one type of complex is formed, which has two tin tetrachlorides and two diesters per complex molecule.
