Adamantylazoles: XII. Alkylation of 1-R-tetrazole-5-thiones and 1-R-tetrazol-5-ones with tertiary alcohols in sulfuric acid
摘要:
1-R-Substituted tetrazole-5-thiones reacted with adamantan-1-ol in sulfuric acid to give mesoionic 1-R-3-(1-adamantyl)tetrazolium-5-thiolates, isomeric 1-R-5-(1-adamantylsulfanyl)tetrazoles, 1-R-4-(1-adamantyl) tetrazole-5-thiones, and 1-R-3-(1-adamantyl)-5-(1-adamantylsulfanyl)tetrazolium salts. Adamantylation of 1-R-tetrazol-5-ones under analogous conditions afforded only the corresponding mesoionic 1-R-3-(1-adamantyl)tetrazolium-5-olates. Mesoionic 1-R-3-tert-butyltetrazolium-5-thiolates and 1-R-3-tert-butyltetrazolium-5-olates were obtained by alkylation of the same substrates with tert-butyl alcohol in sulfuric acid.
