Proton NMR studies in some cyano-biphenyls, oxy-cyano-biphenyls and PAA at atmospheric pressure
نویسنده
چکیده
Dipolar splitting AH from proton-NMR experiments in 5-BCB, 5-8 OCB and PAA are presented and compared with the quantity Z, calculated from refractive index data, in the same set of compounds obtained by Bunning et al. [3]. According to these authors the quantity Z is rather insensitive to the biaxial terms in the ordering matrix and gives the best indication currently available of the temperature dependence of S~~ in these materials.

Abstract: The reactive 1:1 intermediate produced in the reaction between cyclohexyl isocyanide and electron- deficient acetylenic esters or dimethyl acetylene dicarboxylate was trapped by 2-cyano-N-(Aryl) acetamides to provides highly functionalized oxopyridine (potential synthetic and pharmaceutical interest ) in acetonitrile under mild reaction conditions at ambient temperature after 24 h ...

2014 The structures of liquid crystal phases of three members of the series have been determined. All have nematic phases with extremely weak pseudo-layer density fluctuations and the two lowest members have bilayer smectic B type structures in which tails and cyano end groups are interdigitated. There also exist in the SB structures pronounced local modulations probably of a polar antiphase na...

Water is a versatile solvent in many ways, and in this sense performing organic reactions in this medium is now of great interest. The one-pot reaction of ethyl acetoacetate or benzyl acetoacetate, with benzaldehydes and malononitrile to provide some novel 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates has been performed over nano MgO with high performance in water as a green solvent a...
