Formation of β,β-dihaloenones from halogenated tertiary alkynols
摘要:
Halogenated alkynols react with N-halosuccinimides and catalytic amounts of Koser's reagent to afford mixed beta,beta-dihaloenones, useful templates for aryl and alkyl substituted enones.
Formations of mixed β,β-dihaloenals from halogenated secondary alkynols
摘要:
Iodine and Koser's reagent have been used in stoichiometric amounts to convert 3-bromo-1-phenylpropynol to (Z)-3-bromo-3-iodo-2-phenylpropenal in high yield. The latter is a major component of reaction mixtures of 3-iodo-1-phenylpropynol and bromine with Koser's reagent.
