In that period reactions of isocyanides of particular importance were the formation of tetrazole derivatives from isocyanides and hydrazoic acid developed by Oliveri-Mandala and Alagna in 1910 [15, see also 16] and the first three component reaction of the isocyanides (P-3CR) introduced by Passerini in 1921 [1, 9, 17, 18].

Tetrazoles are medicinally important heterocycles incorporated in a large number of drugs [15-16].
These findings and the existance of wel known tautomerism between tetrazole and azido forms in a lot of tetrazoles, are leading us to suggest the rapid equilibrium of each forms 4 and 5 with the azide form 3 as shown in Scheme 3 as a reasonable mechanism for explanation these observations.
* Expandex tetrazoles for high-melting thermoplastics such as PC, nylon, thermoplastic polyesters (PET, PBT), ABS alloys, PPE/ PPO alloys, PPS, and polysulfone; Expandex 5-PT has a foaming range of 464 F and higher.
