Generation and trapping of cyclopropyldiazonium and diazocyclopropane in the nitrosation of cyclopropylamine with alkyl nitrites
Diazocyclopropane and an cyclopropyldiazonium ion, which are highly reactive intermediates, can be generated and trapped by appropriate substrates immediately in the direct nitrosation of cyclopropylamine with alkyl nitrites. Diazocyclopropane is trapped
Mild, rapid, and inexpensive microwave-assisted synthesis of allylic and propargylic esters
A variety of allylic and propargylic esters were rapidly prepared via microwave heating of their corresponding mixed anhydride derived from pivaloyl chloride. The reaction conditions were modified to account for the sterics of the alcohol and the electronics of the carboxylic acid. Supplemental materials are available for this article.
