The intramolecular nature of the shift was shown by the fact that no cross-product was isolated when a mixture of salts was allowed to react. Sulfonium salts are likewise rearranged. Wittig 3 proposed that by the proton capturing influence of the base, an ylid VI is formed which isomer- izes to the final product.

The ammonia-free partial reduction of substituted pyridinium salts Article (PDF Available) in Organic & Biomolecular Chemistry 4(6) April with 80. Publisher Summary. This chapter discusses the sulfur analogues of the alcohols and their derivatives.

The focus of the chapter is on thiols, mercaptans or alkyl hydrosulfides; sulfides or thio-ethers, such as dialkyl sulfides and alkenyl and alkynyl sulfides; derivatives of alkanesulfenic acids, dialkyl disulfides or alkyldithioalkanes, alkylthiosulfuric acids, and sulfonium compounds.

Co 2 (CO) 8-mediated intermolecular Pauson–Khand reactions of N-substituted maleimides with terminal alkynes are described, producing maleimide-fused transformation differs from other intermolecular Pauson–Khand-type reactions of electron-deficient olefins, which react with Co 2 (CO) 8 and alkynes to produce conjugated dienes, or generally require terminal Cited by: 1.

In the first step, the pyrylium salts are converted with the amines into N-substituted pyridinium salts, which, in the second step, react with Nu⊖ to give the desired products RNu.

band, due to intramolecular bonding, increases with strengthening of the intermolecular bond 0H.e.B in complexes of the type OH**-OH-*-B. The same behaviour has been observed for complexes RCOOHB formed by salicylic acid and N-substituted anthranilic acids with proton acceptors; with an.
