Two routes can offer the first stannylene cyanide [(L)SnCN] (5); the substitution reaction of either stannylene amide [(-Bu)ATISnN(SiMe)] (3) or stannylene pyrrolide [(-Bu)ATISn(NCH)] (4) using an excess of trimethylsilyl cyanide (L = aminotroponiminate (ATI)). Using 0.1-2.0 mol% of compound 5, catalytic cyanosilylation of a variety of aliphatic and aromatic aldehydes was achieved at rt-50 °C in 0.33-2.0 h. The mechanism of this catalytic reaction is authenticated by the isolation of a structurally characterized intermediate.

Reactions of EtP adducts of bissilylated germylenes and stannylenes with gold, silver, and copper cyanides led to cyanogermyl or -stannyl complexes of the respective metals. In the course of the reaction the phosphine moved to the metal, while the cyanide migrated to the low-coordinate group 14 element. The respective gold complexes were found to be monomeric, whereas the silver and copper complexes exhibited a tendency to dimerize in the solid state.

Condensation of 5 with 2-methyl-(2-acetamido-3,4,6-tri-O-acetyl-1,2-dideoxy-beta-D-glucopyra no)-[2,1-d]-2-oxazoline in 1,2-dichloroethane in the presence of p-toluenesulfonic acid afforded the disaccharide derivative methyl 3-O-(2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-beta-D-glucopyranosyl)-2, 4,6-tri-O-benzyl-beta-D-galactopyranoside (6) Deacetylation of 6 in methanolic sodium methoxide afforded the disaccharide derivative 7, which was acetalated with alpha, alpha-dimethoxytoluene to afford the 4',6'-O-benzylidene acetal (10). Catalytic hydrogenolysis of the benzyl groups of 7 afforded the title disaccharide 8.
