The exploratory workshop held in February, 1990, at the EXXON Education Center in New Jersey, focused on programs that are being developed by industry and academia to improve middle school science education. As a result of this seminal workshop additional workshops are being held. Information from these workshops will be used in an intersociety project initiated by Paul Gassman, Past President of the American Chemical Society, to produce and disseminate a comprehensive survey of education programs. 

In 1974, Paul Gassman and co-workers recognized the potential of the described rearrangement and reported a one-pot, general method for the synthesis of indoles based on the rearrangement of the nonisolable aza-sulfonium ylides. In the very first example of this method, aniline 4 was treated sequentially with f-BuOCl, methylthio-2-propanone 5 and triethylamine to provide methylthioindole 6 in 69% yield. Raney-nickel-mediated desulfuriza-tion afforded 2-methylindole 7 in 79% yield.
