REFERENCES

• Reagent for diazo transfer to ketones, e.g. under phase-transfer conditions, giving better yields of sterically-hindered ɑ-diazo ketones than other methods: Synthesis, 368 (1980); J. Am. Chem. Soc., 102, 6626 (1980); 113, 2598 (1991); Tetrahedron, 43, 5677 (1987).
• Also used for azide transfer to potassium enolates (KHMDS) to form the ɑ-azido derivatives: J. Am. Chem. Soc., 109, 6881 (1987); 112, 4011 (1990); Tetrahedron Lett., 28, 6141 (1987). Other bases tend to favor diazo transfer. For further discussion and examples, see: Encyclopedia of Reagents for Organic Synthesis, L. A. Paquette, Ed., Wiley, Chichester (1995), vol. 7, p. 5174.
