  Highly efficient microwave assisted α-trichlorination reaction of α-methylated nitrogen containing heterocycles

  摘要：

  A new methodology permitting the chlorination of different alpha-methylated nitrogen containing heterocycles into N-alpha-trichloromethylated derivatives is described here. The combination of microwave technology with a PCl5/POCl3 protocol has allowed to reach trichloromethyl derivatives with high yields in a few minutes. (c) 2006 Elsevier Ltd. All rights reserved.

  Provided are an ultraviolet-sensing sheet, an ultraviolet-sensing set, and an ultraviolet-sensing method, in which color gradation properties which are suitable for detecting an ultraviolet dose are obtained and in which the coloring of an ultraviolet-sensing layer caused by the effect of light other than ultraviolet light is prevented. An ultraviolet-sensing sheet 1 includes: a filter layer 10 that selectively allows transmission of light having a specific wavelength; and an ultraviolet-sensing layer 20 that includes a capsule including a color-forming dye and a photooxidant. It is preferable that the filter layer 10 has a maximum value of the transmittance in a wavelength range of 300 nm or longer and shorter than 380 nm.
