  Induction of Cholesteric Mesophases by Simple Cyclic Derivatives of p,p‘-Disubstituted 1,2-Diphenylethane-1,2-diols:  Importance of Shape and Polarizability Effects

  摘要：

  A systematic study of the cholesteric induction in nematic solvents (MBBA and E7) by some cyclic derivatives of unsubstituted and p,p'-disubstituted-1,2-diphenylethane-1, shows that the values of the twisting power are significantly dependent on the nature of the link connecting the two oxygen atoms and on the nature of the p,p'-substituents. This result has been interpreted considering that the nature of the bridge affects the overall molecular shape and the p,p'-substituents affect both the molecular polarizability and shape. This investigation points out that the polarizability of the solute and the solvent is the main parameter in determining the value of the twisting power while electrostatic arene-arene interactions contribute to a less extent. It has been also observed that solutes having the same structure and the same absolute configuration can induce cholesteric helix of opposite sign depending on the substituent on the aromatic ring. This finding indicates that configurational assignments by cholesteric induction are reliable only if high values of twisting power are measured.

  Provided are a method for efficiently producing an asymmetric conjugated diyne from an inexpensive and safe alternative compound to hydroxylamine hydrochloride and a method for producing a Z,Z-conjugated diene compound from the asymmetric conjugated diyne compound thus obtained. More specifically, provided is a method for producing an asymmetric conjugated diyne compound comprising a step of subjecting a terminal alkyne compound (1): HC≡C—Z 1 —Y 1 to a coupling reaction with an alkynyl halide (2) Y 2 —Z 2 —C≡C—X by using sodium borohydride in water and an organic solvent in the presence of a copper catalyst and a base to obtain the asymmetric conjugated diyne compound (3): Y 2 —Z 2 —C≡C—C≡C—Z 1 —Y 1 . In addition, provided is a method for producing a Z,Z-conjugated diene compound by reducing the resulting asymmetric conjugated diyne compound, or the like.
