John P. Morgan; Elizabeth E. Torres; Richard Averill; Alex M. Brody – Journal of Chemical Education, 2023
The benzoin condensation of benzaldehyde is a staple of the undergraduate organic chemistry laboratory, introducing the current topic of nucleophilic carbene organocatalysis. Our procedure makes notable improvements to current practice, including the elimination of solvent waste and an "18-fold reduction of reaction time." We have…

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…
