The reactivity of the cyanine dyes towards nucleophilic reagents is currently being tested. As in the case of phosphine derivatives, carbanions attack the electrophilic C3 carbon of the pentamethine chain to give, with a good yield, new functionalized podands with cyano, keto, amino, amido, or enol-

Iodosobenzene tetrafluoroborate 1 has been prepared by the reaction of PhI(OAo)p and aqueous BRF4, and its reactions with alkenes, sllyl enol ethers, and aoetylenes have been studied. A considerable number of hypervalent Iodine reagents have been developed in the last oentury, and many of these have
