Abstract: Electrically conductive polymers derived from heterocyclic polycyclic monomers formed of at least two cycles of five condensed members, each cycle containing one heteroatom, as well as a method of electrochemical polymerization by anodic oxidation of these monomers. These polymers may become part of composite electroconductive material.

Abstract: Disclosed herein are antisecretory agents represented by the formula ##STR1## wherein R.sup.1 is hydrogen and R.sup.2 is lower alkylthio, (2-thienylmethyl)thio or SCH.sub.2 -- COOR.sup.5 wherein R.sup.5 is hydrogen or lower alkyl, or R.sup.1 and R.sup.2 are independently a lower alkylthio or (2-thienylmethyl)thio, or R.sup.1 and R.sup.2 together with the carbon atom to which they are attached form a 2-imidazolidinylidene; and R.sup.3 and R.sup.4 are each the same lower alkyl, or R.sup.3 and R.sup.4 together with the carbon atoms to which they are attached form a cyclohexane wherein said carbon atom is a spiro atom in common with the cyclohexane ring and the adjoining dioxane ring.

Abstract: The present specification provides novel analogs of carbacyclin (CBA.sub.2), 6a-carba-prostacyclin (6a-carba-PGI.sub.2), which have pronounced prostacyclin-like pharmacological activity, e.g., as platelet anti-aggregatory agents. Specifically the novel chemical analogs of CBA.sub.2 are those substituted by fluoro (C-5), alkyl (C-9), interphenylene (C-5), methano (C-6a,9), and an additional (olefinic) valence bond (C-6a,9). Further provided are benzindene analogs of CBA.sub.2 and substituted forms thereof, i.e., 9-deoxy-2', 9-methano (or 2', 9-methano)-3-oxa-4,5,6-trinor-3,7-(1',3'-interphenylene)-PGF.sub.1 compounds. Also provided are a variety of novel chemical intermediates, e.g., substituted bicyclo[3.3.0]octane intermediates, and chemical process utilizing such intermediates which are useful in the preparation of the novel CBA.sub.2 analogs.

Abstract: Mono- or bis(iodonium salts) are produced in neutral organic solvents by the reaction of an [hydroxy (organosulfonyloxy)iodo]arene with a bis(triorganosilyl)arene, a bis(trihalosilyl)arene, or with a mono- or bis(triorganosilyl)heterocyclic compound, or a mono- or bis(trihalosilyl)heterocyclic. The iodonium salts are made under conditions of regiospecific control.

Abstract: Novel complexes of macrocyclic polyethers such as 1,4,7,10,13,16-hexaoxacyclooctadecane (18-crown-6) and disulfonates of the formula I ##STR1## wherein X represents barium or strontium and R.sup.1 is an alkylene moiety, optionally substituted with an alkyl group, are described as well as a process for isolating said macrocylic polyethers through formation of said novel complexes. In the isolation process disclosed, a macrocyclic polyether containing solution is contacted with a disulfonate of formula I to afford the polyether-disulfonate complex as a solid suspension in the solution, the suspended complex is separated from the solution and the separated complex is extracted with a solvent for the macrocyclic polyether.
