ABSTRACT: A new and versatile protocol for converting alcohols into alkyl iodides utilizing PPh3
/I2
CHCOCHI2
is
established. Under mild and neutral conditions, this reagent produced higher product yields when compared to
PPh3
/CI4
in the iodination of various alcohols. Competitive reactions with selected iodinating agents and CBr4
in 1H
NMR studies showed that the reactivity of I2
CHCOCHI2
was greater than general I2
/imidazole and N-iodosuccinimide
(NIS). Consequently, the PPh3
/I2
CHCOCHI2
condition provides one of the attractive alternatives for iodination.
