摘要:
The reaction of 1-phenyltetrazole-5-thione with adamantan-1-ol in sulfuric acid gave 3-(1-adamantyl)-1-phenyltetrazole-5-thione having a mesoionic structure, 5-(1-adamantylsulfanyl)-1-phenyltetrazole, and 3-(1-adamantyl)-5-(1-adamantylsulfanyl)-1-phenyltetrazolium hydrogen sulfate. Hydrolysis of 5-(1adamantylsulfanyl)-1-phenyltetrazole led to the formation of 1-phenyltetrazol-5-one. The adamantylation process is reversible.
