Abstract
Flash vacuum pyrolysis (FVP) of 5-azido-1-aryltetrazoles results in triple N 2 elimination and formation of aryl isocyanides RNC, which rearrange in part to aroylnitriles RCN under the reaction conditions. Similar FVP of 5-azido-1-arenesulfonyltetrazoles generates a compound absorbing in the IR spectrum (77 K) at 2090 cm -1 and assigned the structure of arenesulfonyl isocyanide, ArSO 2 NC 11 . FVP at temperatures above 600 o C results in progressively more nitrile ArSO 2 CN 12 . Compound 11 also disappears on warming above -80 o C
