Abstract:

A process for preparing 3-hydroxyoxetane comprising the following steps in order (1) reacting a carboxylic acid of the formula CH. sub. 3 (CH. sub. 2). sub. n COOH with epichlorohydrin in the presence of anhydrous ferric chloride to produce an ester of the formula ##STR1## wherein n is an integer of from 0 to 3; (2) protecting the secondary hydroxy group of the ester with a blocking group, Z, that is stable to bases; thus forming a blocked ester of the formula ##STR2## (3) hydrolyzing the blocked ester formed in step (2) with an aqueous base to remove the carboxylic acid and form a 3-hydroxyoxetane derivative of the formula ##STR3## in which Z represents the blocking group; (4) removing the blocking group from the 3-hydroxyoxetane derivative by heating it with an alcohol and an acid to form the product 3-hydroxyoxetane, ##STR4##.

US Classification:

526282

Abstract:

1,3-Diethynyladamantane and a method of forming same by brominating adamantane to yield 1,3-dibromoadamantane, subjecting vinyl bromide to Friedel-Crafts alkylation with the 1,3-dibromoadamantane to form 1,3-bis(2,2-dibromoethyl)adamantane and subjecting the 1,3-bis(2,2-dibromoethyl)adamantane to dehydrohalogenation to yield the 1,3-diethynyladamantane. 1,3-Diethynyladamantane can be polymerized to produce strong, thermally stable resins suitable for advanced aerospace structural applications, as matrices for carbon-carbon systems and as electrical insulators. It can also be copolymerized with 1-ethynyladamantane to yield similarly useful resins.

Abstract:

A perfluoroalkylene. alpha. ,. omega. -diacetylene compound having a fluorocarbon chain of from 5 to about 20 carbon atoms between two acetylene end groups, and a method of forming same by first reacting perfluoroalkylene diiodide having the formula I(CF. sub. 2). sub. n I, wherein n is a whole number from 5 to about 20, inclusive with bis(trimethylsilyl)acetylene, and converting the reaction product to the diacetylene with KF. The diacetylene has the general formula HC. tbd. C(CF. sub. 2). sub. n C. tbd. CH, wherein n is as set forth above, and it can be polymerized to produce a clear, hard, cross-linked resin suitable for use as a coating on bearings and in the manufacture of aircraft windshields. Monofunctional counterparts of the HC. tbd. C(CF. sub. 2). sub. n C. tbd. CH compounds can be formed by substituting perfluoroalkyl primary iodides for the diiodides in the above-described reaction.
