Many pyrans are less stable or less accessible than pyrylium salts or pyranones but some suitably substituted 4//-pyrans can be used to prepare pyridines. Ethyl 6-amino-5-cyano-2,4-diphenyl-4H-pyran-3-carboxylate (196) on heating with ammonium acetate gives the corresponding pyridine-3-carboxylate (195), but when the ester group in (196) is replaced by a cyano group, a dihydropyridine (197) is obtained by a different and more complex reaction (81JHC309).

In this section the use of polystyrene and copolymers of styrene with various cross-linking agents as supports for solid-phase organic synthesis is discussed. Copolymers of styrene with divinylbenzene are the most common supports for solid-phase synthesis. Depending on the kind of additives used during the polymerization and on the styrene/divinylbenzene ratio, various different types of polystyrene can be prepared. However, non-cross-linked polystyrene has also been used as a support for organic synthesis [10,16-22], Linear, non-cross-linked polystyrene is soluble in organic solvents such as toluene, pyridine, ethyl acetate, THF, chloroform, or DCM, even at low temperatures, but can be selectively precipitated by the addition of methanol or water.

The above-mentioned salts and some other compounds (NH3, pyridine, ethyl-enediamine, butylamine, ethanol, methanol, dioxane, dimethylformamide) were also added to solutions containing 0.04 Ni(CN) and 0.98 M KCN. Relatively small concentrations of all these compounds result in a decrease of absorbance between 375 -500 nm. Since ammonia has nearly the same effect as fluoride ion or dioxane, the authors rejected the possibility of further complex formation (such as Ni(CN)5F ), and explained the observation as a strong decrease of activity coefficients corresponding to the mass action expression ...

A good solvent for PLA and for most of the corresponding copolymers is chloroform. Other solvents are chlorinated or fluorinated organic compounds, dioxane, dioxolane and furan. Poly(rac-lactide) and poly(meso-lactide) are soluble in many other organic solvents like acetone, pyridine, ethyl lactate, tetrahydrofuran, xylene, ethyl acetate, dimethylformamide, methyl ethyl ketone. Among non-solvents, the most relative compounds are water, alcohols e.g. methanol, and ethanol) and alkanes e.g. hexane and heptane) [7]. [Pg.441]
