Indene reactions: An organic chemistry laboratory problem

Abstract

Students are given a problem in which they are to determine which of two published accounts of reaction products involving derivatives of idene is correct.

Three puzzles for organic laboratory

“…One of the reasons that so few organic lab courses display any problem orientation is the absence of appropriate exercises. Only two papers giving good problems for this approach seem to have been published (4,5) although some other organic experiments have some puzzle component (6- 14). Therefore, in this paper, we offer three puzzles, each of which can be solved using melting points alone, and each of which involves work at the 100-200-mg scale, a scale which still allows the use of conventional glassware, but which has the speed and safety of truly micro work.…”
