酮与稳定膦叶立德在家用微波炉中加热，在无任何溶剂或固体介质条件下，4．5min之内完成反应，得到了良好产率的Wittig反应产物，较之液相苯中回流反应的传统方法，此法具有时间短、操作步骤简单、无毒害等优点，同时使一些在传统方法中与稳定叶立德不反应或难反应的酮得以进行并有较好收率。此外，在得到α，β-不饱和酯的同时，还发现了少量重排产物β，γ-不饱和酯，并对其机理进行了推测与证明。     

Chiral Parameter of Transparent Films Containing Polymer Cholesteric Liquid Crystal-R

The transparent film containing a kind of polymer cholesteric liquid crystal-R was fabricated by the freezing method. The optical polarization response of the film was investigated by a self-manufactured apparatus and its optical rotatory dispersion was measured by a novel technique at the wavelength from 35Onto to 66Onto.At various wavelengths, the chiral parameter of the film has been obtained. The results show that the chiral parameter decreases as the wavelength increases. The maximum and minimum chiral parameters are 0.0343 at the wavelength of 350 nm and 0.0058 at the wavelength of 660 nm, respectively. The obtained data indicate that this kind of polymer cholesteric liquid crystal-R is a promising candidate host material for solid optical chiral waveguides.
