Feng, Jingjing; Cao, Jian; Abbas, Rizwan; Tao, Minli – Journal of Chemical Education, 2021
A functionalized fiber (PAN[subscript ADMAP]F) was synthesized by immobilizing "N,N'"-dimethyl-"N"-(4-pyridinyl)-1,3-propanediamine (ADMAP, a DMAP analogue) onto the surface of polyacrylonitrile fibers (PANF). The structure and morphology of the functionalized fibers were characterized by Fourier transform infrared…

Martin, Eric; Kellen-Yuen, Cynthia – Journal of Chemical Education, 2007
A greener, microwave-assisted Wittig reaction has been developed for the second-semester organic teaching laboratory. Utilizing this microwave technique, a variety of styrene derivatives have been successfully synthesized from aromatic aldehydes in good yields (41-68%). The reaction not only occurs under neat reaction conditions, but also employs…
