By employing easily accessible 2-alkynylanilines and the well-established fluoroform-derived CuCF3 reagent, a novel class of 3-(trifluoromethyl)indoles could be synthesized in good yields with no ambiguity of the CF3 position. The method utilized a domino cyclization/trifluoromethylation strategy to construct the indole cores with the concomitant installation of the CF3 group. The ultimate source of CF3 is the low-cost industrial byproduct fluoroform (CF3H). The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Related Products of 157869-15-3

On September 22, 2011, Murthy, A. V. R.; Goel, Mahima; Patil, Shivprasad; Jayakannan, M. published an article.Computed Properties of 146370-51-6 The title of the article was Probing the Role of Chain Length on the Diffusion Dynamics of π-Conjugated Polymers by Fluorescence Correlation Spectroscopy. And the article contained the following:

We investigate the role of the chain length and mol. weight distribution on the diffusion dynamics of freshly synthesized MEH-PPV polymer chains. For the above purpose, a new technique based on combination of size exclusion chromatog. (SEC) with fluorescence correlation spectroscopy (FCS) is developed to probe the diffusion dynamics of a narrow mol. weight distribution of fractionated samples of 20-500 kDa. The narrow dispersed samples were characterized by absorbance, emission, and time-resolved fluorescence decay techniques. The results revealed that the properties of fractionated samples were almost uniform for a wide range of mol. weights A maximum entropy based method for FCS data anal. is employed to obtain the correct diffusion coefficients of the polymer chains with heterogeneous dynamics. The FCS experiment on the unfractionated broad mol. weight sample is not enough to establish the correlation between the mol. weight of the chains with diffusion dynamics and emphasized the need for relatively monodispersed π-conjugated polymers. FCS results show that higher mol. weight chains diffuse much faster than shorter ones. Atomic force microscopy revealed that 300 kDa polymers produced 130 nm particles, whereas 50 kDa polymer chains formed micrometer size aggregates. At higher mol. weights, the strong chain interactions promote the formation of globular (or tightly packed) particles which diffuse faster in solution The low mol. weight chains experience strong interparticle interaction; as a consequence, the diffusion of chains becomes slower. In the present investigation, we demonstrate the need for the narrow polydisperse sample for establishing the correlation between diffusion dynamics and chain length (or mol. weights) of π-conjugated polymers using a single mol. spectroscopy technique such as FCS. The experimental process involved the reaction of 1-((2-Ethylhexyl)oxy)-4-methoxybenzene(cas: 146370-51-6).Computed Properties of 146370-51-6
