Iodides acids

A variety of fluorinated alkenyl zinc reagents such as CF2=CFZnCl, CF2=CHZnCl, E and Z-RCF = CFZnCl have been prepared by the first method (Scheme 54). In the presence of palladium catalyst, these fluorinated alkenyl zinc reagents undergo cross-coupling reactions with aryl iodides, vinyl iodides, acid chlorides and 1-iodo-l-alkynes to give the corresponding fluorinated alkenyl derivatives [127, 146-153], which have been utilized in the synthesis of fluorinated codlemones [154]. Typical examples are outlined below (Scheme 55). 

Treatment of polymer films by reactive gases or reactive volatil compounds allows to easily modify polymers containing alcohols, hydroperoxides, carboxylic acids (or acids halides), double bonds or piperidine groups. New functional groups as organic nitrites, nitrates, iodides, acid halides (Cl, F), amides, esters, peresters and nitroxyl radicals can be generated by a single reaction or by combination of two consecutive treatments. The reactions are very efficient on thin films (ca 50-100 pm) and can be controlled by transmission and reflexion 1R spectroscopy.

Carbon-centred free radicals may be formed readily either directly from [bis(acyloxy)iodo]arenes, thermally or photochemically, or from added precursors such as alkyl iodides, acids and alcohols, mediated by DIB, BTI or a [bis(acyloxy)iodo]arene. Table 4.7 presents approaches applied for the generation of free radicals in this way. 

The method described is essentially that of Smith.1 Several other workers have used a similar method.2 Cetyl iodide has also been prepared by heating cetyl alcohol with yellow phosphorus and iodine in carbon disulfide solution,3 and by repeatedly passing dry hydrogen iodide acid into the molten alcohol and permitting the reaction mass to stand between additions.4... 

With acids this salt loses potassium iodide, KI, and yields an acid. This acid has the constitution of an inner salt and would be related to what we may term the normal tetra-methyl ammonium iodide acid, by the loss of hydrogen iodide, and to a tetra-methyl ammonium...

The synthesis sequence of a Claisen rearrangement and a 1,3-cycloelimination was developed by Marc Julia, and turned out highly relevant to pyrethroid chemistry. [87] Methallyl alcohol is etherified with the methyl enol ether of methyl laevulinate. After the subsequent Claisen rearrangement, the keto-group is selectively reacted with methylmagnesium iodide. Acid hydrolysis leads to iso-pyrocine, a central building block, which is also accessible by other routes. Con-...
