H. Monenschein et al., Reactions of alkenes, alkynes, and alkoxyallenes with new polymer-supported electrophilic reagents, ORG LETT, 1(13), 1999, pp. 2101-2104
Preparation of new polymer-supported electrophilic reagents that efficientl
y promote 1,2-haloacetoxylations of alkenes and alkoxyallenes is described.
Under very mild conditions and in high yields, alkenes are transformed int
o or-halo acetates while alkoxyallenes lead to vinyl iodides. In contrast t
o these results, terminal alkynes commonly afford synthetically valuable l-
iodo-alkynes.
