Schmidt M, Bauer A, Schmidbaur H.
PMID: 11669821
Inorg Chem. 1997 May 07;36(10):2040-2043. doi: 10.1021/ic961410k.

Maleic and phthalic acids are found to react with Be(OH)(2), generated in situ from BeSO(4)(aq) and Ba(OH)(2)(aq), in aqueous solution at pH 3.0 or 4.4, respectively (25 degrees C), to give solutions containing the complexes (H(2)O)(2)Be[(OOCCH)(2)] (1) and (H(2)O)(2)Be[(OOC)(2)C(6)H(4)]...

We have investigated the heterogeneous interaction between a number of carboxylic acids and soot generated from different fuel sources and formation mechanisms. A low-pressure fast flow reactor in conjunction with ion drift-chemical ionization mass spectrometry detection was employed to...

Degradation of phthalic acids by denitrifying, mixed cultures of bacteria.

Mixed cultures of bacteria, enriched from aquatic sediments, grew anaerobically on all three isomers of phthalic acid. Each culture grew anaerobically on only one isomer and also grew aerobically on the same isomer. Pure cultures were isolated from the...

Synthesis of Multisubstituted 1-Naphthoic Acids via Ru-Catalyzed C-H Activation and Double-Alkyne Annulation under Air.

The Journal of organic chemistry

Chen H, Ouyang L, Liu J, Shi WJ, Chen G, Zheng L.

J Org Chem. 2019 Oct 18;84(20):12755-12763. doi: 10.1021/acs.joc.9b00926. Epub 2019 Jun 25.

An efficient [2 + 2 + 2] benzannulation of phthalic acids/anhydrides with two alkynes was developed for synthesis of multisubstituted 1-naphthoic acids via Ru-catalyzed C-H activation. The reaction preceded well using atmospheric oxygen as the sole oxidant with high...

Selective Host-Guest Co-crystallization of Pyridine-Functionalized Tetraphenylethylenes with Phthalic Acids and Multicolor Emission of the Co-crystals.

Chemistry (Weinheim an der Bergstrasse, Germany)

Feng HT, Xiong JB, Luo J, Feng WF, Yang D, Zheng YS.
PMID: 27739616
Chemistry. 2017 Jan 12;23(3):644-651. doi: 10.1002/chem.201604133. Epub 2016 Dec 05.

Tetraphenylethylene (TPE) and its derivatives are the most typical and most widely studied organic compounds showing aggregation-induced emission (AIE). Due to their propeller-like structures, V-like clefts exist between the aryl rings, which make them promising host compounds. However, such...

Separation of o-, m- and p-phthalic acids by high-field asymmetric waveform ion mobility spectrometry (FAIMS) using mixed carrier gases.

Journal of mass spectrometry : JMS

Barnett DA, Purves RW, Ells B, Guevremont R.
PMID: 10972997
J Mass Spectrom. 2000 Aug;35(8):976-80. doi: 10.1002/1096-9888(200008)35:8<976::AID-JMS25>3.0.CO;2-Q.

Baseline separation of the three isomers of phthalic acid was achieved in a mixed gas system containing a 95 : 5 mixture of N(2) and CO(2), even though the acids could not be distinguished by high-field asymmetric waveform ion...

Bacterial Decarboxylation of o-Phthalic Acids.

Applied and environmental microbiology

Taylor BF, Ribbons DW.
PMID: 16346440
Appl Environ Microbiol. 1983 Dec;46(6):1276-81. doi: 10.1128/aem.46.6.1276-1281.1983.

The decarboxylation of phthalic acids was studied with Bacillus sp. strain FO, a marine mixed culture ON-7, and Pseudomonas testosteroni. The mixed culture ON-7, when grown anaerobically on phthalate but incubated aerobically with chloramphenicol, quantitatively converted phthalic acid to...

Organic Acid specificity for Acid-induced ATP synthesis by isolated chloroplasts.
