Abstract
The reaction of o-azidobenzaldehyde 1 with TPP at 0°C leads to the expected iminophosphorane 2 and the indazole derivative 3 while at −20°C the phosphazide 4 was the only reaction product. The close related compounds 2 and 4 shows stricking differences in reactivity towards primary amines.
