Abstract: Disclosed is a process for the coproduction of (1) an alkyl iodide and (2) an .alpha.-iodocarboxylic acid, a mono-.alpha.-iodocarboxylic anhydride or a mixture thereof which comprises contacting a mixture of an iodine compound and a carboxylic anhydride with a peroxide at an elevated temperature.

Abstract: Disclosed is a process for the preparation of .alpha.-iodocarbonyl compounds such as .alpha.-iodocarboxylic acid anhydrides and .alpha.-iodoketones by the reaction of a carboxylic anhydride with molecular iodine. Hydrolysis of the .alpha.-iodocarboxylic acid anhydrides gives the corresponding .alpha.-iodocarboxylic acids.

Abstract: The new compounds produced from a molecular structural element with two chirality centers and at least one mesogenic structural element are defined by the general formula (I) ##STR1## in which the symbols have the following meaning: Y.sup.1 =H, (C.sub.1 -C.sub.10)alkyl, MC--CH.sub.2 or MC--CO, MC denoting the molecular radical of a mesogenic carboxylic acid after splitting off a COOH group,Y.sup.2 =(C.sub.1 -C.sub.10)alkyl, MC--CH.sub.2 or MC--CO, it being possible for Y.sup.1 and Y.sup.2 to jointly represent a MC--CH group, which is then part of a dioxolane ring,X=COOR.sup.1, CONH.sub.2, CONR.sup.2 R.sup.3 or C.tbd.N,R.sup.1 =(C.sub.1 -C.sub.10)alkyl or MC--CH.sub.2, andR.sup.2, R.sup.3 =H and (C.sub.1 -C.sub.4)alkyl or, independently of each other, (C.sub.1 -C.sub.4)alkyl.Said esters preferably find application as dopants in twistable liquid crystal phases in which they produce temperature compensation and twisting.

Abstract: Pharmaceutical compositions of the prodrug type, a process for the preparation thereof, a process for the preparation of the as prodrug functioning compounds and compounds obtained herein.The pharmaceutical compositions of the invention contain organic acid anhydrides with formula 1 through 5, as well as the pharmacological acceptable salts thereof as prodrug functioning compounds, together with a suitable pharmaceutically acceptable gaseous, liquid or solid carrier.The prodrug systems of the invention possess as favorable property that they amend the residence time of the pharmaceutical composition in the body by influencing the transport system.Furthermore they increase the biological availability because of the more lipophilic properties of the anhydride compared with the acid, so that this improved administration performance may contribute to lower dosages.
