Säurederivate der Tetrachlorterephthalsäure

Abstract: Diester der Tetraohlorterephthdeiure wurden als potentielle Weiohmwher duroh Umsetzung von Tetrachlorterephthaloylohlorid mit einem tfbareahus von Alkoholen oder Phenolen dargestellt. Weiterhin wurden von der Tetrachlorterephthdsiiure synthetisiert : der Bis( /?-rhodano&thyleatm), der Diaoetwigester, der Dithiolester, dtls Diamid und DinitriL uber Verbindungen der Tetrachlorterephthalsaure ist im Gegensatz zu denen der perchlorierten Phthalsiiurel) bisher wenig bekannt geworden. 1896 stellte Bupps) erstmalig T… Show more

“…The alkyl tetrachloroterephthalate esters are more resistant to saponification than are the corresponding tetrachlorophthalate esters as observed here and by Profit and Timm (10). While accurate neutralization equivalents could be obtained for di-n-propyl tetrachlorophthalate in aqueous ethanol after 2 hr using a standard procedure ( 8), the same procedure with dimethyl tetrachloroterephthalate gave neutralization equivalents about 20-40% high, indicating incomplete saponification.…”

“…Preparations of these diesters and others, some containing aromatic and halogenated aromatic nuclei, are described here. A comparison of properties of many of these compounds with the tetrachlorophthalates (8) is of further interest since both classes of materials are potential plasticizers (10,12).…”

“…dimethoxybenzamide (1) [9, 121, was prepared in 28% overall yield from o-vanillin by iodination of its mercury salt according to the method of Profft and Pannach [14], subsequent 0-alkylation with dimethyl sulfate, followed by oxidation of the produced iodobenzaldehyde with AgN03 [9], which was converted to 1.9 g (62%) the benzamide 3 [8] as an oil via its acid chloride as (m-n-butyltinl-N-[( 1 -ethyl-2-pyrrolidinyI)methyl]-2.3-dimethoxybenzamide (2) (0.025 mL, 43 nmol), made by dissolving 50 mg of 2 in 50 mL EtOH. Concentrated HCI (0.025 mL, 0.30 mmol) was added at 23 OC.…”
