Abstract

The preparations and thermal rearrangements of 2-alloxybenzoxazole, 2- alloxybenzothiazole, 5-alloxy-lphenyltetrazole, 5-crotoxy-l-phenyltetrazole, and 5-a- methalloxy-1-phenyltetrazole are described. P-Alloxypyrimidine was prepared and upon heating it gave only traces of rearranged product. Neither 2-alloxypyrimidine nor 3-alloxy-1- phenylpyrazole underwent rearrangement at temperatures sufficient for the ...
