- In the presence of base (e.g. KO-t-Bu) in an aprotic solvent, e.g. DME, ketones are cyanated to give the homologous nitriles; see, e.g.: Org. Synth. Coll., 6, 41 (1988). Hindered ketones can be cyanated in DMSO: J.

- Successive alkylation with different alkyl groups, followed by acid hydrolysis, leads to unsymmetrical ketones: Tetrahedron Lett., 4229 (1977). Similarly, dialkylation with ɑω-dihalides gives cyclobutanones: Synthesis, 325 (1980), or larger-ring ketones: Tetrahedron Lett., 22, 4193 (1981). Reaction of monoalkylated TosMIC with ɑω-dihalides is a useful route to 1,5- or 1,6-diketones: Rec. Trav. Chim., 104, 50 (1985):

Pyrroles are also formed by reaction with aldehydes followed by either ethyl cyanoacetate to give 3-cyanopyrroles: J. Org. Chem., 57, 2245 (1992), or nitromethane to give 3-nitropyrroles: Tetrahedron, 47, 4639 (1991); Synthesis, 871 (1996). The same products are also obtained by reaction of TosMIC with nitroalkenes, from Henry reaction of the aldehydes with nitromethane:
- In contrast, aldehydes with K2CO3 in refluxing methanol lead to high yields of 5-substituted oxazoles: Tetrahedron Lett., 2369 (1972); with acid chlorides, the corresponding 4-tosyl oxazoles are obtained.
