A novel metal-free tandem oxidative coupling process for the synthesis of hemiaminal ethers has been developed. This protocol could be applied for the C–N bond formation of electron-deficient trizoles, tetrazoles, carbazoles and indazoles with primaryalcohols.
Tetrazole derivatives of the formula ##STR1## wherein R is a substituted or unsubstituted phenyl group, heterocyclic group, or benzo-fused heterocyclic group, which exhibit activity as insecticides and acaricides.

1-Benzyl-5-aryltetrazoles were discovered to be novel antagonists for the P2X(7) receptor. Structure-activity relationship (SAR) studies were conducted around both the benzyl and phenyl moieties. In addition, the importance of the regiochemical substitution on the tetrazole was examined. Compounds were evaluated for activity to inhibit calcium flux in both human and rat recombinant P2X(7) cell lines
The present invention provides novel compounds which may be used as in vivo imaging agents. The compounds of the invention are useful in a method to image the expression of P2X
7
receptors in a subject, as a means to facilitate the diagnosis of a range of disease states.
