Azides of the heavier Group 13 elements

摘要

The current knowledge about azides of the heavier Group 13 elements is reviewed. Only neutral compounds of the general formula R_(3-x)M(N_3)_x(D)_y and MN_3 (M = Al, Ga, In. Tl; R = organic or inorganic substituent; D = neutral donor; y = 0-3) are taken into account. The syntheses of Group 13 azides of the formal oxidation number +III can either be achieved by salt metathesis, a bond metathesis, or substitution reactions. The synthesis, structures, properties, and applications of mono-, di-, and triazides including inter- and intramolecular donor-stabilized compounds are discussed.
