ChemInform Abstract: Alkynyliodonium Salts as Alkynylating Reagents: Direct Conversion of Alkynylphenyliodonium Tosylates to Dialkyl Alkynylphosphonates with Trialkyl Phosphites.

The treatment of various alkynyl(phenyl)iodonium tosylates 1 (R=t-Bu, s-Bu, i-Pr, cyclopentyl, Ph, and p-MeC 6 H 4 : X − =OTs − ) with neat trimethyl phosphite gave the dimethyl alkynylphosphonates 4a and 4d-h in isolated yields ranging from 34 to 90%. Similar treatment of 1 (R=t-Bu, X − =OTs − ) with neat triethyl and triisopropyl phosphites gave the diethyl and diisopropyl alkynylphosphonates 4b (81%) and 4c (58%). The byproducts of these reactions are alkyl tosylates and iodobenzene

ChemInform Abstract: A Convenient Synthesis of 1‐Aminopolycycloalkanes and Their Tosylate Salts.

AbstractThe polycyclic carboxylic acids (I) are converted to the corresponding amides (IV) and then treated with hydroxytosyloxyiodobenzene (V) in acetonitrile at room temperature, forming the intermediate iodonium tosylates (VI) which are cleaved upon heating to produce the ammonium tosylates (VII).

ChemInform Abstract: Crystal Structure of a Novel Tricoordinate Vinyliodinane Species and Evidence for an Alkylidenecarbene‐Iodonium Ylide.

AbstractReaction of the iodonium tosylate (I) with the ammonium phosphate (II) gives the zwitterionic species (IIIa) which, after recrystallization, is a head‐to‐tail dimer (IV) in the solid state according to X‐ray analysis (space group P1 with Z=2).

ChemInform Abstract: Acetylenic Esters. Preparation and Characterization of Hitherto Unknown Alkynyl Carboxylate, RCCOCOR′, and Alkynyl Phosphate, RCCOPO(OR′)2, Esters.

AbstractThe synthesis of the title compounds (IV) and (VIII) is accomplished by anion exchange of the known iodonium tosylates (I) with the species (II) or (VI) to give the new iodonium salts (III) (not isolated) or (VII) ((VIIa) can be isolated, (VIIb) cannot be obtained in pure form).
