摘要:The present invention is concerned with a method of synthesizing certain ##STR1## 3-disubstituted sulfam(na)phthalein compounds useful as pH-sensitive indicator dyes and with intermediates useful in the preparation of said compounds. The subject method comprises (1) reacting (a) a 3,3-disubstituted sulfam(na)phthalein wherein one of the 3-substituents is a 4'-hydroxy-1'-phenyl moiety or a 4'-hydroxy-1'-naphthyl moiety substituted in the 3'-position with a perhalomethylcarbinol group and (b) an acid halide, ##STR2## wherein R is alkyl or aryl to give (c) an acylated intermediate wherein the N atom of the sulfam(na)phthalein ring and the 4'-hydroxy and carbinol hydroxy groups are acylated with ##STR3## and (2) treating said compound (c) with alkali to selectively remove said ##STR4## from said hydroxy groups and yield the ##STR5## product. The intermediates of the present invention are the acylated compounds (c).

摘要:This invention relates to a method of synthesizing certain 3-(carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxides (and -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) by reacting (a) a 4-OP-carbocyclic aryllithium compound wherein P is a protecting group and (b) a 3-(carbocyclic aryl)benz[d]isothiazole-1,1-dioxide wherein said 3-(carbocyclic aryl) moiety is other than a 3-(4'-OP-carbocyclic aryl) moiety to give (c) the corresponding 3-carbocyclic aryl)-3-(4'-OP-carbocyclic aryl)-2,3-dihydrobenz[d]isothiazole-1,1-dioxide. The -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides are prepared in the same manner by reacting a 3-(carbocyclic aryl)naphtho[1,8-de]-1,2-thiazine-1,1-dioxide with said 4'-OP-carbocyclic aryllithium compound. n In a further embodiment, the compounds synthesized according to the foregoing method are reacted with a carboxylic acid halide to give the corresponding 2-carbonyl-substituted 2,3-dihydrobenz[d]isothiazole-1,1-dioxide (or -2,3-dihydronaphtho[1,8-de]-1,2-thiazine-1,1-dioxides) followed by removing the protecting group, P, with weak acid to yield certain phenol and 1-naphthol sulfam(na)phthaleins useful, e.g., as optical filter agents and filter agent precursors in photography.

摘要:Various embodiments of the present invention relate to a method of preparing coordination polymer crystals, and to the crystals produced thereby. The method includes providing a composition. The composition includes Component (i), a metal-containing compound that is a source of one or more metal ions; Component (ii), a bridging ligand-containing compound that is a source of one or more bridging ligands; Component (iii), a first liquid in which (i) and (ii) are soluble; and Component (iv), a second liquid immiscible with the first liquid. The method includes mixing the composition to form an emulsion. The method also includes maintaining the emulsion for a time sufficient to produce a crystalline coordination polymer. Various embodiments also provide methods of making membranes and membranes made thereby wherein the membrane-forming composition includes the coordination polymer crystals, including methods of making membranes wherein coordination polymer crystals form in the membrane or in the membrane-forming composition before, during, or after curing of the membrane-forming composition. Various embodiments also provide methods of gas separation using the membranes.
