Recently, we demonstrated that triphenylacetic acid could be used to seal dye molecules within MOF-5, but guest release required the digestion of the framework by treatment with acid. We prepared the sterically bulky photocapping group [bis-(3-nitro-

We have developed a simple strategy allowing molecular guests to be trapped within MOF-5 using carboxylic acids bearing sterically demanding substituents as capping reagents. We demonstrate that introducing triphenylacetic acid or diphenylacetic acid

Ti3O(OiPr)6(OOC-adamantyl)4 and Ti3O2(OiPr)3(OOCCPh3)5 were obtained from the reaction of Ti(OiPr)4 with adamantylcarboxylic or triphenylacetic acid, respectively. The structures of both are based on a central Ti3O unit, which is substituted by diffe

Knudsen mass-loss effusion technique was used for measuring the vapor pressures at different temperatures of the following crystalline compounds: diphenylacetic acid, between 357.27 and 379.08 K; triphenylacetic acid, between 418.98 and 436.97 K; 2,2

The photolysis of methyl triphenylacetate in methanol gave biphenyl, methyl α-methoxyphenylacetate, methyl benzoate, and methoxydiphenylmethane. The formation of these products suggests that two types of α,α-elimination take place: One is the elim

Organic compounds, such as triphenylacetic acid, triphenyl ethylene, and triethyl phosphite can be selectively fluorinated in dimethylsulfoxide/ HgF 2 solutions under UV-visible illumination. Product yields, determined by 19 F-NMR, are essentially qu

Triphenylacetic acid is isomorphous with the published structure of triphenylchloromethane (I). It crystallizes in the trigonal system, space group P3, with a=b=14.105(3)A, c=13.121(2)A V=2261(1)A3, Z=6 at 175K. The structure was solved by direct met
