Novel reagents containing hypervalent iodine and their use for electrophilic additions to olefins

Abstract A series of novel I(III) containing reagents have been developed and their electrophilic reactions with olefins giving vic -disubstituted derivatives (including vic -ditriflates) are described.

Novel method of deoxidation of alcohols and its use in synthesis of covalent perchlorates

Abstract Alcohols can be effectively deoxidated by treatment with chlorine and sulfur in the presence of pyridine with incorporation of an external nucleophile from added salts.

COMPETITIVE BINDING OF FLUOROSULFATE ANION IN REACTIONS OF HALOGENS AND NITRONIUM BOROFLUORIDE WITH OLEFINS

ConclusionsReactions of olefins with chlorine in the presence of fluorosulfonic acid salts lead toβ-chloroalkyl fluorosulfates together with 1,2-dichlorides. The addition of nitronium borofluoride to ethylene in the presence of tetraethylammonium fluorosulfate gives 2-nitroethyl fluorosulfate. These reactions confirm the general character of the competitive binding of superweak nucleophiles in AdE reactions.
