Cyclohexyl isocyanide (1 mmol) and / -fluorobenzoyl chloride (1 mmol) were heated neat for 1 h in a CEM microwave at 60 °C (50 W) and finally dissolved in toluene (2 mL). To this solution was added ZnCh in THE (0.1 mL of a 1 M solution) followed by the addition of phenyl tetrazole (1 mmol, 1 equiv). The reaction mixture was then heated overnight at 80 °C.

Substances 557 derived from structure 554 (Scheme 168) have been described (Scheme 169). The structure of 3-methyl-5-phenyl-tetrazole 1-oxide monohydrate 557 (R=Ph, Aik=Me, H20) has been determined by X-ray crystallography (1993PJC1767). H NMR, C NMR, and MS data are also available (1993PJC1767). 

We have already discussed the acidity of NH-tetrazoles 61 to form tetrazolate anions 62 [75], In the same paper, we also studied the protonation. The substituent X strongly affects the tautomeric balance between 1,3-H,H+- (82) and 1,4-H,locations (84). In the case of electron-withdrawing substituents, the most preferred form of the conjugated acid is the 1,3-H,H+- form (82) structures 83 and 85 are much less stable. The acidity measures in solution and in the gas phase satisfactorily correlate with each other. In all cases, these relationships do not hold for 5-phenyltetrazole (56, X = Ph). This could be explained by the difference in solvation of this compound compared to other 5-X tetrazoles as well as by some peculiarity of its electronic structure, for example, the strong conjugation between the phenyl substituent and the tetrazole ring.
